| The idea behind this test is that the underline should be |
| completely obscured by both the selected and unselected text. |
| |
| Note that the former is not yet actually tested here, because |
| originating decoration recoloring essentially makes it |
| impossible to tell whether the text or underline is on top |
| (this can be fixed by highlighting the unselected text with |
| some other highlight pseudo, so recoloring doesn’t apply). |
| |
| Chromium fails in /c/2902289 and passes in /c/2903387. |
