**Steps to replicate the issue** (include links if applicable):
* Enable HotCat
* Visit https://commons.wikimedia.org/wiki/File:20230509_Luzon_daytime_overflight_09.jpg
* Attempt to add Pasig River and see the whole list
**What happens?**:
* The top of the list is unavailable. We can only choose categories from the bottom of the list.
**What should have happened instead?**:
The purple circled area is where the bug happens... well we just can't get to see the top of the list.
**Software version** (skip for WMF-hosted wikis like Wikipedia):
**Other information** (browser name/version, screenshots, etc.):
You might say "Don't bother us with a bug in a gadget."
But in fact I think the gadget is a victim of a bug in MediaWiki!
It is just doing its thing within a MediaWiki box that cuts it off.
And as we are at the top of the page, there is no room left...
