The [X] on the link modal in the editor is confusing

[magicroundabout]

This is a UI/UX issue with the pop-up link modal.

It's common design pattern to have a cross icon on a modal to close the modal. In the pop-up link modal in the editor the X DELETEs the link, rather then closing the modal. The number of times I've accidentally deleted a link is really confusing. Here's the visual:

I know that there's a tooltip that says "delete", but once I've seen the [X] it's easy to go straight for it and click before my being processes the tooltip content.

I also know that the correct action for closing the modal is to click "somewhere else", but this has no affordance.

Suggestions:

• Use a text "Close" label instead of/as well as the [X]
• Add an extra icon, like a trashcan or something, for delete, make the [X] close the modal.

Add an extra icon, like a trashcan or something, for delete, make the [X] close the modal.

Could we reuse the ​existing Unlink icon?
