fix(compositor): clear old position with last known dimensions #38229

Browse Source 
Problem:  When reconfiguring a float reallocates the grid before the old
          area is cleared, artifacts are left on the screen.
Solution: Use the last known compositor dimensions of a grid when
          clearing the area covered by the old position.
