[Bug] MobileNav: closing the drawer skips the slide out animation

Description

When closing MobileNav on mobile, the drawer disappears instantly instead of sliding out. Opening works fine and animates smoothly, but closing has no visible transition at all.

Would be good to get eyes on this since MobileNav's animation is being referenced as the model pattern in #4174.

Reproduction

1. Open the mobile nav drawer (opening is animated correctly)
2. Close it via backdrop click, close button, or Escape
3. Drawer vanishes immediately, no animation

Example is available at the playground here Its the second example from the docs
