Visual bug, a pheromone selection menu will show on xenos while overwatching click their pheromones button.

### Issue Bingo

- [x] Issue could be reproduced at least once
- [x] Issue happened in a recent (less than 7 days ago) round
- [x] Couldn't find an existing issue about this (https://github.com/cmss13-devs/cmss13/issues)

Start by reproducing the issue with an overwatched xeno, then trace the select pheromone button from the xeno UI to the radial menu behavior. The payload names no files or tests, so locate the relevant UI entry point first. Done means the pheromone selection menu does not appear over an overwatched xeno and normal pheromone selection remains unaffected.
