StatusBubbleViews in chrome is a place that needs to be updated to use the aura::Window property directly and not WmState.

Turns out we only need to change this property during window construction. So, we should instead rename the property to kWindowIgnoredByShelf_InitProperty and simplify code.

The following revision refers to this bug:

Renames kWindowIgnoredByShelf_Property to ..._InitProperty

We only need to set this during initial window creation, so set rename
the property appropriately and update code as appropiate.
