Thread:VisualEditor/Feedback/Adding a link to an image caption

I seem to be unable to easily add a wikilink to an image caption using VisualEditor. When I open the "Media settings" window to edit the caption, I can click the "Link" button to add a link, but then the program doesn't seem to think I've actually made any changes to the caption, because it won't let me click the "Apply changes" button. Am I doing something wrong, or is this a bug?
