Command Palette has no style applied

[wildworks]

Originally reported in the Gutenberg project: ​https://github.com/WordPress/gutenberg/issues/52097

Command Palette, bundled into the core in WordPress 6.3, works as a feature but has no styles applied at all. Perhaps the enqueue of styles in script-loader.php is leaking.

Expected behavior

Trac ticket: https://core.trac.wordpress.org/ticket/58667

As far as I can tell, the CSS for the command package for the Command Palette feature is bundled with the core. However, they do not appear to be enqueued.

✅ In the Site Editor, the CSS with id wp-commands-css should be enqueued

✅ In the Post Editor, the CSS with id wp-commands-css should be enqueued

✅ If the language is RTL, the CSS with id wp-commands-rtl-css should be enqueued

✅ These CSS should not be enqueued in the Block Widget Editor and Customized Widget Editor

In 56125:

Editor: Enqueue commands package styles.

Enqueues the stylesheet from the commands package which holds the CSS for the Command Palette feature.

Props wildworks.
Fixes #58667.
