Reland "[Minimal UI] Fix missing updates of non-draggable area"

This is a reland of commit 4a0ef9479a4b855c515324686c6bf173f87f6cce

Original change's description:
> [Minimal UI] Fix missing updates of non-draggable area
>
> In the initial CL non-draggable area is not updated when view
> is in the process of layout. This is incorrect logic that migrated
> from prototyping, because width changes of the layout indicate
> that we're in the active layout phase, thus area was never updated.
>
> This CL removes isInLayout check, because we always receive signals
> in the active layout phase and after view has changed its bounds.
>
