Note that this may vary depending on the text (or more probably the length of the text) in the tab. I wonder if the transparent gradient/fade of the text in these tabs plays a part here. I will attach a video screen capture of this happening. One URL that causes it is the URL of a previous bug I reported: https://bugs.freedesktop.org/show_bug.cgi?id=55484 (the tab in the video uses this one).
