Steps to replicate the issue (include links if applicable):

• skin: vector-2022
• visit https://test.wikipedia.org/w/index.php?title=User:Novem_Linguae/Scripts/GANReviewTool/GARLog&action=edit&useskin=vector-2022
• use a high browser zoom or a small screen
• click "preview"
• scroll to top of page

What happens?:

• panel has narrow height and a scroll bar

What should have happened instead?:

• panel should have normal height and no scroll bar. this is more intuitive behavior for this kind of panel. it fits on the screen fine so it should be fixed height, and the user can scroll the main page down to see anything that is cut off.

Software version (skip for WMF-hosted wikis like Wikipedia):

Other information (browser name/version, screenshots, etc.):

• fix may involve CSS overflow-y
