Comment (by flixos90):

 This is a duplicate of #62345 which provides additional context for the
 problem.

 Per what is outlined in that ticket, it's worth clarifying that this is
 not a Chromium bug. The HTML specification itself outlines in
 https://html.spec.whatwg.org/multipage/rendering.html#img-contain-size the
 CSS rules that are provided by the user agent stylesheet, so putting
 `width: content-fit` on those images violates the spec, so it would be an
 error in WordPress or the theme that uses it.

 It's worth checking how widely this problem comes up, if we're able to
 gather any metrics on this, and then deciding on the next steps. But a
 revert of the entire feature should only be considered if it's widespread
 and no reasonable alternatives exist. Since it's not a Chromium bug, the
 browser behavior in that regard won't change. On the other hand, it is
 still unclear to me why `width: fit-content` is needed.
