Title labels and default description too long

Thanks for this report! Does the small modification to the CSS in the staged merge request resolve the issue for you?

I noticed the same problem on our sites and the merge request solves the problem (even if the Insert/Update button becomes a bit too small, at least the content doesn't flow outside of the modal)

The merge request definitely makes it much better. But as the previous commenter also noted, it still cuts off the Insert/Update button a little.

Also, personally, I feel like the LinkIt popup is unnecessarily narrow. It would be nice if it could automatically expand a little wider on larger screens.
