I can confirm this bug on my VM with similar steps as in comment #0. Generally you just have to open a few tabs, click on Panorama, drag one of the tabs out its group, then select it and hover over the Fx icon in the taskbar, followed by hovering on the tab previews.

Depending on the number of tabs you have open, this can look really bad. It's not a permanent problem, as the overlapping goes away as you hover on other thumbnails.
