[Bug] [Breakdown] Black highlight left behind text after deleting an element from left Elements panel

[hyuri]

If I have an element added to a piece of text, and I delete the element from the left Elements panel, the text remains highlighted but now with black.

Deleting from the right (scene) Elements panel does not cause the issue.
