12.0p/12.1p/13.0d Calendar event length in Firefox always a tiny bit too long

[Blama]

Hi Isomorphic,

please see these unmodified samples in 12.0p/12.1p/13.0d.
The event length in Firefox 91 always a tiny bit too long. This does not happen in Edge 93.
Tested with FF 91.0.2 with no browser zoom under Win10 with 250% system zoom on a 4K (3840 × 2160) display.

Similar issue for the scrolling enabled by scrollToWorkday: true, that scrolls a tiny bit too far. Again, this does not happen in Edge.
In both cases it is more than a pixel off, so I assume this is not zoom related (?).

Hi Isomorphic,

this seems to be event length (and some multiplication?) related. You can see this by putting two events next to each other that end at the same time, but one is much longer and starts earlier.
Or just look at the Day lane sample and Tamara Kane.

Hi Isomorphic,

just as an FYI: It does not happen with v12.0p_2021-09-16 on a Win10 FullHD display with no system zoom using Firefox 92.
So it seems not only browser zoom, but also system zoom is a problem, at least for Firefox.
