Seems like grid code isn't happy with a calc() value in track-related CSS properties

[Simon Fraser (smfr)]

Maybe caused by :
--grid-column-width: calc((100vw - var(--container-outer-width) * 2 - var(--grid-gap) *(var(--grid-column-count) - 1)) / var(--grid-column-count));

Is this possibly fixed by r285232? I can't repro on MiniBrowser Debug.

New Assert Logs

I am not able to get same assertion logs using URL from Comment 0 but these and it also lead to crashing MiniBrowser WK2 Debug instance based of 259136@main.

[Ahmad Saleem]

It is reproducible for me with (278291@main) on https://invisioncommunity.com/
