I am seeing a rendering glitch on the following page: <https://github.com/solson/miri/pull/262>

Steps to reproduce:
* Hover the word "Fixes"
-> a "tooltip" appears explaining things
* Move the mouse elsewhere

Expected behavior:
The tooltip disappears.

Actual behavior:
The tooltip leaves behind a horizontal black bar where the bottom of the tooltip used to be.  I will attach a screenshot.

This is with 56.0a1 (2017-07-19) (64-bit) on Linux, Debian testing amd64, Intel video card.

(I wasn't sure whether Bugzilla or Webcompat are the right venue for this bugreport.  Please let me know if I should report elsewhere.)

Is this a recent regression?

I do not know.  I have not seen this before, but I also have not ever looked at this particular tooltip before.

It does not happen in FF 54.

I can reproduce it in fx57 when e10s is disabled.
