Fixes: #47165

What?

This PR fixes console errors output when moving the mouse in FireFox.

Why?

I was unable to find the root cause, but as this video shows, I discovered that the mouse move event also detects text nodes. The text node does not have a classList, resulting in a console error.

How?

Checking if the node type is a text node.

Testing Instructions

  • Open the site editor in FireFox.
  • Enter edit mode for any of the templates.
  • Move the mouse cursor to confirm that the browser console error does not appear.

I've noticed that the inserter also appears in browse mode in firefox. I guess it's unrelated with this PR though.

Thank you for the review!

I've noticed that the inserter also appears in browse mode in firefox. I guess it's unrelated with this PR though.

I was able to reproduce this problem with trunk and have submitted #47190. I would like to merge this PR as I believe it isn't the cause of the problem.
