7.4 inline editing with ie 11

just upgraded to 7.4 on my dev machine, I need to test for accessibility before doing this in production.

testing inline editing which runs ok with chrome but with IE 11 I got a different experience

From detail view, I double click on the text area of a field, actually it was a drop down and the drop down appears … with a green checkmark at the right to confirm.
so I modify the record and click on the check box.
the field has been updated but I have a misterious “undefined” hyperlink that appears.
if I click on it, nothing happens, if I double click on it even if I am close to the right field, the field comes back in editing mode.

I do not experience this with chrome.

how to solve?
