Fix for https://bugzilla.mozilla.org/show_bug.cgi?id=1449982#c75 - the assertion in UpdateZoomConstraints is no longer accurate, since with GPU process and async-scene-building enabled in WR, it can get called on the compositor thread in the GPU process, which is not the updater thread.
Bas was hitting this assertion failure in his local debug windows build with WR enabled.

If the GPU process is disabled but WR + async scene building are enabled, this can also happen on the UI process compositor thread receiving a message over PAPZCTreeManager, can't it? (That is, the removal of the assertion is fine, but the comment is still misleading.)
(In reply to Botond Ballo [:botond] from comment #4) > If the GPU process is disabled but WR + async scene building are enabled, > this can also happen on the UI process compositor thread receiving a message > over PAPZCTreeManager, can't it? Yup, you're right. I'll update the comment.
