Updating focus manually when the multi-step focus is active causes race condition

## Description

The multi-step focus sometimes makes it impossible to focus vertex manually. This is caused by the race condition when the `isVertexFocused` in the `VertexFocusContextType` is updated in the `VertexFocusProvider` but the `MultiStepVertexFocusProvider` still sees the old value and updates the focused vertex position and scale.
