Defining custom colors in styles color palette removes other colors from palette in several block editor places

[burnuser]

Defining custom colors in styles - "color palette" removes all other colors from palette in inline formatting (highlight) and other block editor places.

This problematic bug has been reported several times in Gutenberg:
​https://github.com/WordPress/gutenberg/issues/64857

Since the (longstanding) bug shows effect in the block editor, but seems to be caused in styles - "color palette" and is still unresolved in WordPress 6.7-beta1-59156 (Theme: Twenty Twenty-Four), maybe trac would be the correct place to draw attention to it?
