[chromium] Work around null render surface crash in updateCompositorResources
Created attachment 108728 [details]
I plan to land this on the 874 branch. Bugzilla's not really equipped to make that obvious.
An alternate approach would have been to clear m_updateList in setRootLayer, since this is the place where render surfaces are cleared. Or, since m_updateList is in use in paintLayers, mark some flag that it needed to be cleared, since it's in use in that function. However, I wanted something simple on the branch so it only had to be fixed once, so I just added a conditional check.
