I only see timings after reloading the plugin

- browse to a gitlab ci job (e.g. https://gitlab.com/xtofl/fixtopt/-/jobs/205502171)
- I see only a thick red line at the bottom
- create new tab at url `about:debugging`
- press 'Reload' in the GitLabTimings plugin section
- go back to the ci job page -> now the timings appear in blue
