Accessibility: Improve toggling the "Post locked" information visibility.

- effectively hides the "Post locked" information from assistive technologies
- when a post is locked, reveals the "Post locked" information without CSS animation
- the height CSS animation didn't work anyways after [24906]

See #24553.
Fixes #44946.
