Created attachment 8712290 [details] arrow-heap.gif When expanding a node, the arrow doesn't change until you were to collapse it again, and then it has an expanded arrow. A bit out of sync. gif helps
Created attachment 8712297 [details] arrow.fxsnapshot Seems like it might just be for dominator trees. Use this snapshot.
Has STR: --- → yes
Priority: -- → P3
Probably missing a check of some prop in `DominatorTreeItem.shouldComponentUpdate()`. I think Julian found something similar recently, but I can't find the bug...
Marking as duplicate of Bug 1241070, feel free to reopend if I'm mistaken. All my try pushes had a permafail on unrelated performance mochitests, so I wanted to investigate that before asking for checkin. Other than this the fix is ready :/
