Automatically assigning owner based on suspected regression changelist https://chromium.googlesource.com/chromium/src/+/1b35e9d3c88b00383159550e9e1bc4e39face107 (Remove SetVisible from WebLayerTreeView, set it from within content.).

If this is incorrect, please let us know why and apply the Test-Predator-Wrong-CLs label. If you aren't the correct owner for this issue, please unassign yourself as soon as possible so it can be re-triaged.

This is a CHECK that shm is valid, which I don't think is going to fall from where we set visible on the compositor.. so => author of the CHECK.
