CKEditor issue after upgrade to 5.4.0

[Fleiding]

I just upgraded from 5.3.4 to 5.4.0 and for some reason an annoying X appears in the CKEditor on my custom style (not on the vB default styles).



If I inspect the element, I see the following code:

<span class="b-icon b-icon__x-circle--dark js-link js-contententry-panel-x h-margin-right-m h-margin-top-m js-ckeditor-toolbar-close" tabindex="0">x</span>

I tried searching for this line in the Admin Control Panel, but was not able to find this line.

Is there any way I can hide it using CSS?

Have you tried clearing the browser cache?

Yes, no effect.

Do you have template merge conflicts after the upgrade? One of them might be containing that X button.

I did have template merge conflicts, but I just noticed the X appears on a fresh install of vBulletin 5.4.0, so I will contact the theme maker to take a look.
