Comment 9

[Patrick Brosset <:pbro>]

This test was added more than a year ago and was running fine until recently. Started to fail very seldomly about a month ago, and now much more for the past 2 weeks.
There hasn't been any changes made to the test that would explain this.
The test seems to be failing only on Windows debug and asan (slow environments), and as far as I can see, the test times out while waiting for the grid-highlighter-shown event. This event never seems to be fired, so the test just ends up waiting until it times out.

Micah, when you get a chance, could you please take a quick look at this one? 
It might be hard to reproduce locally, but since you originally worked on it, maybe an idea comes to mind as to what could be the problem here.

Julian, can you please take a look?

Comment 53

[Julian Descottes [:jdescottes]]

It seems that from time to time, we get an extra reflow when the inspector starts and the "grid inspector item" we attempt to hover is being re-rendered while we call:

  EventUtils.synthesizeMouseAtCenter(
    gridCellA,
    { type: "mouseover" },
    doc.defaultView
  );

gridCellA is the response to an async call to waitForDOM, but before using it we actually wait for a bunch of other events (onCheckboxChange, onHighlighterShown), so there are lots of opportunities to get an intermediary render.

An easy fix should be to fetch a fresh copy of the element we want to hover before calling synthesizeMouseAtCenter.
At least it fixes it for me locally.

Comment 54

[Julian Descottes [:jdescottes]]

Going to apply the same fix on the similar test (browser_grids_grid-outline-highlight-cell.js) tracked by Bug 1501317.

Not completely convinced but the two tests are almost identical. Seems like a mess to maintain those 2 identical copies.
