Coordinates placement is inconsistent between browsers when using Vector 2022 on projects that display the coordinates using absolute positioning rather than an indicator.
I originally ran into this when tweaking the styles for coordinates at German Wikipedia: https://de.wikipedia.org/wiki/Wikipedia:Technik/Skin/MediaWiki/Änderungen#c-Hgzh-20221215160900-Matma_Rex-20221215110100 where I had applied a CSS workaround to avoid it: <https://de.wikipedia.org/wiki/MediaWiki:Vector.css#L-38>.
The problem happens because Vector 2022 styles for the page subtitle etc. trigger a confusing edge case with margin/float/clear, which has a different rendering between browsers. At first I filed this as a Chrome bug: https://bugs.chromium.org/p/chromium/issues/detail?id=1401690 but I'm not sure any more if it's really a bug.
Since many projects are affected, maybe we should change out CSS to avoid this.
Examples:
At <https://lt.wikipedia.org/wiki/Krokuva>, the coordinates overlap the edit tabs on Chrome, but not Firefox:
| Chrome | Firefox
| -- | --
| {F35870427} | {F35870429}
At <https://als.wikipedia.org/wiki/Krakau>, the coordinates overlap the infobox on Firefox, but not Chrome:
| Chrome | Firefox
| -- | --
| {F35870435} | {F35870437}
