Can't see reply's timestamp in thread view

### Site

phanpy.social

### Version

2024.12.28.119d4b0

### Instance

merveilles.town

### Browser

Firefox 133 on NixOS unstable

### Bug description

Clicking on the `...` in a reply activates the widget with the fave/boost actions, but also hides the date.

This is particularly troublesome when the post mentions a relative time. like "stream starts in 5 hours".

### To reproduce

1. open any [post that has replies](https://hci.social/@chrisamaphone/113730696758788754)
2. hover over the reply
3. try to read the timestamp

### Expected behavior

Timestamp should be visible, furthermore the user should be able to hover on the humanized timestamp to see the exact date.

### Other

This is doubly annoying because the expected UX for popups is that clicking outside the popup area or pressing `esc` will make it disappear, but that doesn't happen here, quite the opposite. The user has to move the cursor **off of the post** they are trying to view the timestamp of to be able to read the timestamp, which is very counterintuitive, to say the least.

See attached screenshot.
