Subject: [PATCH] Make `mouse_focus` and `mouse_focus_mask` consistent for
 force_drag

In `Viewport::_gui_force_drag` currently `Viewport::gui.mouse_focus`
gets cleared, but `Viewport::gui.mouse_focus_mask` doesn't get cleared.

This is an inconsistency which can cause a crash.

With the change of this PR, `mouse_focus_mask` also gets cleared.
This is in alignment with how regular drag and drop clears both variables.
