Bug 1977581 - Keep activating the parent window on Windows when destroying a child. r=win-reviewers,handyman, a=dsmith

Browse Source 
Bug 1902315 removed a PlaceBehind call here, which in this case happened
to also activate the window (via the aActivate = true parameter).

Keep raising the window manually, but with simpler APIs.
