 ### Bug Fix
 
+-   `UnitControl`: Fix `disabled` style is overridden by core `form.css` style ([#45250](https://github.com/WordPress/gutenberg/pull/45250)).
 -   `Button`: Fix RTL alignment for buttons containing an icon and text ([#44787](https://github.com/WordPress/gutenberg/pull/44787)).
 -   `TabPanel`: Call `onSelect()` on every tab selection, regardless of whether it was triggered by user interaction ([#44028](https://github.com/WordPress/gutenberg/pull/44028)).
 -   `FontSizePicker`: Fallback to font size `slug` if `name` is undefined  ([#45041](https://github.com/WordPress/gutenberg/pull/45041)).
