YouTube also has the problem that there is almost no dead space to "park" your cursor. You have to carefully place it in between autoplaying previews.
This gets doubly frustrating when navigational elements don't contain actual anchor links. If you long-tap on mobile to open in a new tab, the browser decides you are selecting text and there is almost no way to dismiss the resulting copy/etc popup without tapping elsewhere on the page - which you cannot do without navigating elsewhere or otherwise causing an unwanted action.
Accidentally click on some white space? Well too bad, we’ve closed whatever you’re looking at, even though you’re not in a modal. Oh and also, you’ll need to wait 30-seconds for this new page to load, and you can’t just bail out and go back a page, because your browser can’t hold the previous page in cache/memory properly because it’s some overly-complicated JS app.
Then I wonder where the Description and Acceptance Criteria are for the next User Story, because it remembers that you (accidentally) contracted the Description for User Story X therefore you obviously don't want to see it for any others...
