Load https://software.hixie.ch/utilities/js/live-dom-viewer/?saved=7256 The page has a grid container with grid-template-rows: repeat(auto-fill, 10px) [foo] 20px [bar]; Then it logs the resolved value. It logs "10px [foo] 10px [bar] 10px 10px 20px" But it should log "10px 10px 10px 10px [foo] 20px [bar]" This has been already fixed in Chromium https://chromium-review.googlesource.com/c/chromium/src/+/1857125
