Bug 1813980: Check IsDoc before Parent in RemoteAccessibleBase::ApplyCrossDocOffset. r=morgan
We call this function on every ancestor when calculating bounds.
RemoteParent() currently requires a hash lookup, so it's more efficient to early return for !IsDoc() first.
This is a micro-optimisation, but it might have some impact given that we call this on every ancestor, especially when hit testing, where we call Bounds() a lot.
As a bit of drive-by cleanup, use RemoteParent() rather than calling Parent() and IsRemote/AsRemote().
