When working on a whiteboard, I regularly had to access the upper right menu with the styles and zoomin in/out functions. Suddenly (and repetetively), the menu with the account, alert and help buttons placed themselves on top of it, instead of over it. I.e., on the y-axis, they were in the same spot. Making the whiteboard menu inaccessible and with that, the entire whiteboard basically unusable.   Reloading didn't help. Closing the browser did once, but the bug reappeared right after.  

Steps to Reproduce

Not sure - it just kept happening mid-work, but I always only noticed after it happened.
