CkEditor 5 colorplateicon console error

Hello i had the same problem i could not open font color and font background menus. I noticed that some extra code was copied from external editor:

After applying "Remove Format" on this fragment of text both menus have returned to operation.

Pozi can you explian how to apply remove format on ckeditor 5
i am using full html text for my sections

Ran into this too. Issue is related to some bad minimization.

In js/build/font.js:
icon:i.icons.colorPaletteIcon

should be changed to:
icon:e.icons.colorPaletteIcon
