Fix #147487: Disable Area Maintenance Animations

Disabling (at least temporarily) the fading animations shown during and
after some area maintenance routines (like splitting, joining, closing)
as this causes memory leaks during automated testing. This doesn't
occur during regular usage, just when the window is closed within the
animation time. We'll look for an improved solution in the future.
