We could introduce another boolean to prevent changes, or just reuse _active_modifiers_event = true to prevent further update. Additionaly this patch restore the keyboard state when focusing out, which is fine when dealing with full remote desktop, but should be reconsidered if/when SPICE supports remote windows managed by client window manager for instance, imho.
