I mean it clears the inner html of the html title element in the head of the page. You can see this happen on your demo page
. I even stated that I assume it is related to the code responsible for preventing the default browser tooltip. Did you read what I wrote? Sorry for being a bit abrasive but when someone takes the time to report a bug it would be nice if you spent 30 whole seconds trying to recreate it rather than assuming I don't know what I am talking about. You can even see this in action without even launching the dev tools by simply looking at the browser tab. It switches from displaying a title to the pages URL because that is the default behavior when no title is specified. Using chrome and ie to test this so far.
