Note: this behavior is seen in Firefox. Chrome seems to be OK.

On http://en.wikipedia.beta.wmflabs.org/wiki/Media_Interface_VisualEditor_Test?veaction=edit - the link was applied to a specific word(s)?

I tried to follow your scenario with the word Test on that page - "New page/Matching pages" seems to be identical with any attempts.

I cannot reproduce this issue following these steps either.

Created attachment 17124
after invoking Link inspector the first time, before clicking Remove

Attached:

Created attachment 17125
after clicking Remove and then clicking Link inspector again

This is clearly wrong

Attached:

Created attachment 17126
clicking Link no longer invokes the Link inspector at all

Attached:

FWIW, I can repro this consistently in Firefox 32.0.3

Steps to reproduce:

1.Go to this page:http://en.wikipedia.beta.wmflabs.org/wiki/Media_Interface_VisualEditor_Test?veaction=edit

2.Click on link inspector icon from the toolbar , but make sure you do not place your cursor in the article first

3.Once the link inspector opens for the first text "Media" , click on "Done" or "Remove" to close the link inspector.Again, do not place the cursor inside CE

4.Click on link inspector icon from the toolbar again

At this step, you will see a broken UI for link inspector,just the link suggestions are appearing as the screenshot.

Also, after this step link inspector stops working completely, clicking on the link icon from the toolbar does not open link inspector for any other text in the article .

Environment:betalabs,test2, en.wiki

Also, happens when you type a text and select that and try to open link inspector for it
