The grid outline component needs unit tests. These tests should especially verify correctness of extreme case usage of the grid outline.

We should take in account the changes made by bug 1348919 here: since we do not have specific test for the `moveInfobar` function, but we're testing the highlighters that are using it. In the grid outline test, we should add some tests about the grid highlighters' infobars too (e.g. checking that they're hidden when offscreen, and they're properly positioned on top / bottom).
