Describe the bug
When having a list of links, I can select multiple line-items at the same time, which will show the link popover. So it looks like I can edit all those links in my list at the same time. However, if I, for example, set them to "open in new tab", all the links will suddenly point to the same URL. There is no notification of this happening, the anchor text stays the same, it's just the URLs that change.

To reproduce
Steps to reproduce the behavior:

1. Go to edit a post or page
2. Create a list and add links to the list items
3. Select multiple lines
4. Click anything in the popover that pops up after selecting
5. Notice the URLs of the list items now all point to the same URL.

Expected behavior
I was expecting one of two things:

1. For bulk editing not to be possible, so I can't select multiple links and still have the popover show, or
2. If bulk editing should be possible, for the URLs of the links I selected to remain what they were.
