<!-- NOTE: This bug was triggered by scrollbar opacity-fading, so this
|
|
|
|
|
testcase needs to be loaded with this pref...
|
|
|
|
|
layout.testing.overlay-scrollbars.always-visible
|
|
|
|
|
...set to *false* in order to have a chance to trigger the bug.
|
|
|
|
|
|
|
|
|
|
We don't have to worry about this producing any screenshots of
|
|
|
|
|
unpredictable partially-faded-scrollbars in our reftest snapshot,
|
|
|
|
|
because our scrollbars don't actually paint here, since the
|
|
|
|
|
scrollable element has "overflow:auto" and doesn't overflow
|
|
|
|
|
(because it's auto-sized to fit its content). -->
