When we hit the assert the root content document is https://searchfox.org/mozilla-central/rev/dc4560dcaafd79375b9411fdbbaaebb0a59a93ac/testing/mochitest/harness.xhtml . It is basically a xul document, and look xul document it does not have a root scroll frame. The frame we hit the assert on is fixed pos, so it passes the fixed pos part of IsZoomedContentRoot here https://searchfox.org/mozilla-central/rev/dc4560dcaafd79375b9411fdbbaaebb0a59a93ac/layout/base/ViewportUtils.cpp#139 but there is no root scroll frame so it still returns null. We should only his this when there is no root scroll frame. So to fix this I decided to make the existing code conditional on having a root scroll frame and then write a bunch of pretty strong asserts that we are in this exact edge case if we don't have a root scroll frame.
