Due to unresolved T97631 we're facing OOUI whitespace optimized for a base font-size of 12.8px resulting in core's HTMLForms with base font-size: 14px in action visually to spacious.
Let's try to address this specifically.
Examples:
| Before | After |
|---|---|
| Special:Block | - |
| height of .mw-htmlform-ooui of 597.47px | resulting height of 517.22px |
| Special:Blocklist | - |
| 283.53px | 254.41px |
