• Edit a page
• Put cursor at the end of a line
• Go to toolbar and Insert new link
• The input field is focussed, blur it by clicking somewhere inside the inspector outside the input field
• Click the trash can (since there is no "x" close button, that's the closest I can find in the top left or right corner)
• The inspector clears itself but stays behind (crashes half-way closing)

An empty inspector stays behind and the user can no longer interact with any links at this point. When doing anything (scrolling, typing) the inspector will hide. Except the bubble tip on top, that one stays behind...
