We hit assertion which were added by bug 1414713. That tells us an ancient bug.
There is comment which claims that we should move all list items in the right
list node to left list node if the list nodes should be merged. However, this
has never been done actually since 2002. The code tried to move *some* list
items in the right list node to the list list node. However, retrieving first
list item at an offset almost always failed because the offset variable has
never been initialized.
If we believe the comment, we should move all children of the right list node
to the left list node. However, until we get a testcase to reach this case,
we should keep current behavior, i.e., do nothing, for unexpected regression.

EditorUtils::IsDescendantOf() current takes a pointer to offset or a pointer to
child content if the caller needs to know the child of the most ancestor node.
However, some callers should get a child as EditorDOMPoint or EditorRawDOMPoint.
Then, they can be used for some editor methods which need to take child node
for performance optimization.
This patch makes EditorUtils::IsDescendantOf() as only two overloads. One takes
pointer to EditorRawDOMPoint as optional out argument. The other takes pointer
to EditorDOMPoint as an out param.

RangeBoundaryBase shouldn't compute mRef when it's initialized with offset.
E.g., some users of the template class may initialize it with a container and
offset in it but it may not refer mRef or may refer after modifying offset.
On the other hand, RangeBoundaryBase::InvalidateOffset() is a special method.
It assumes that mRef is always initialized when it's called but can be
invalidate mOffset until retrieved actually. This is necessary for
nsRange::mStart and nsRange::mEnd since the offset may be changed when
some nodes are inserted before the referring node.
So, now, InvalidateOffset() should be a protected method and make nsRange a
friend class of RangeBoundaryBase. Then, when nsRange sets mStart and/or mEnd,
nsRange itself should guarantee that their mRefs are initialized.

A lot of methods in editor returns a child offset with an out param when it
returns its container and offset in the container. This is ugly hack for
performance of nsINode::IndexOf(). However, there are a lot of regression
since the relation between offset and child node can be broken really easily.
So, we should make EditorDOMPoint as a subclass of RangeBoundary and manage
a set of container, reference child and its offset in it (e.g.,
SetNextSibling() added by this patch).
Note that RangeBoundary's performance is not good for temporary use if we set
a point with offset, it immediately retrieves mRef. The following patch will
improve this performance.

HTMLEditRules::BustUpInlinesAtRangeEndpoints() tries to split all inline nodes
at range start and range end. It uses EditorBase::SplitNodeDeep() to split
the nodes and HTMLEditRules::GetHighestInlineParent() to retrieve the highest
inline parent of them.
Currently, HTMLEditRules::GetHighestInlineParent() may return editing host or
ancestor of it if active editing host is not block. Then, it may cause
splitting editing host or its parents and following methods of HTMLEditRules
will fail to modify the nodes created outside the editing host.
So, HTMLEditRules::GetHighestInlineParent() should return only one of the
descendants of active editing host.
Unfortunately, even if just adding the test case as a crash test, I cannot
reproduce the crash with automated tests. Therefore, this patch doesn't
include any automated tests.
And this patch changes a crash test, 1402196.html, which expects that an inline
editing host is split by execCommand("insertOrderedList"). However, this patch
fixes this wrong behavior. Therefore, this patch changes the event target of
event listener from <p> inside the editing host to the editing host itself.

Currently, HTMLEditRules::WillInsertBreak() checks if the editing host can
contain a <p> element as a child or a descendant. However, this is not enough.
If an inline element has a block element which can contain a <p> element,
current implementation considers to insert a <br>. This is possible when
* The editing host is an unknown element including user defined element.
* The editing host is an inline element and its children and/or descendants
were added by JS. E.g., <span contenteditable> element can have <div>
element.
I think that we should consider to insert a <br> element when:
- There is no block ancestors in the editing host.
- The editing host is the only block element and it cannot contain <p> element
or the default paragraph separator is <br> element.
- The nearest block ancestor isn't a single-line container declared in the
execCommand spec and there are no block elements which can contain <p>
element.
Note that Chromium checks if CSS box of ancestors is block too. However,
it must be out of scope of this bug.

First, the method name is not correct. It tries to find an editable node near
the given DOM point. Therefore, it should be FindNearEditableNode().
Next, the implementation did something odd. E.g., in the first |if| block,
when |nearNode| is nullptr, it returns nullptr. However, following |if| block
does something only when |nearNode| is nullptr. So, we can get rid of the
second |if| block. Then, nobody will change aDirection. So, we can make it
not a reference now.
Similarly, in |while| block, if |nearNode| becomes nullptr, it returns error.
However, following block checks if |nearNode| is NOT nullptr. So, we can get
rid of this |if| statement and outdent its block.
Additionally, |curNode| isn't necessary. It only increments the refcount
redundantly. So, we can get rid of it.
Finally, FindNearEditableNode() can return found node directly instead of
error code because error code doesn't make sense. Not found an editable
node is not illegal. And also it can take EditorRawDOMPoint instead of
a set of container, child and offset of the child in the container.
