vis: Add navigation and help text for dmesg-warning lines
After #68 (closed) we no longer have an immediate indicator that we have warnings in dmesg. The test result being dmesg-warn or dmesg-fail is a clue but it could be said it requires arcane knowledge of our testing internals, and other test results (incomplete, skip, timeout) don't carry such information. In addition, navigating to the warning lines cannot be done easily.
- Add a help test to the test result page that indicates that the dmesg row contains warnings. For example, it could be under the "Dmesg" heading like in
- Add a navigation button to scroll down to the first warning. This requires marking the first such warning with an id in the
pre
-element for an anchor and adding a button somewhere (maybe same place as above) to go to that anchor.
