[FIX] Correct Inline reactions behaviour

[aKn1ghtOut]

Proposed changes (including videos or screenshots)

The $().data function was returning outdated values for re-assigned emoji buttons with new data. Changed that to use the .attr() function. This works perfectly.

Issue(s)

Closes #20734

Steps to test or reproduce

1. React to a message
2. React to the same message again using a different reaction
3. Click the first reaction. It disappears.
4. Click the only remaining reaction. The first reaction reappears.

This works like a charm.
