Description Cole 2023-01-27 13:47:29 PST 
Live reproduction can be viewed here: https://codesandbox.io/s/lucid-margulis-3c7v8e?file=/index.html

Note that the `div` elements (visualized with a blue border) take on the intrinsic widths of their image children, rather than the computed image width (as expected). This currently also fails on Firefox (see https://bugzilla.mozilla.org/show_bug.cgi?id=1344525), but performs correctly on Chrome, where the divs are sized according to their image child's computed width.

Setting `display: contents` on the `div`s does resolve this layout issue, but prevents any styles from being applied to the `div`s themselves, and also breaks scroll snapping behaviour if the flex container is set to allow its contents to overflow with scrolling.

This affects the layout too. 

section div {
  height: 100%
}

There's another bug on Mozilla bug for this. I can't find it right now.
