BUG - Color Popup "OK" Button/dialog closes table cell popup/dialog

[s4ke]

We use the editor in a page that has tables in it. When we want to change the background color of a cell, we go to the cell settings:

then, we click on background color:

select color, click on OK.

Cell editor is gone and page has a gray overlay and we can't edit anymore:

My hunch says that there is something wired up weirdly either in our app, or in one of the recentupdates of this package that causes the second popup to close all existing popups. Would be awesome, if you could give us some pointers how we could improve this situation.

We are on the latest version of djangocms-text-ckeditor (5.1.5).
