It normalizes the values without the quotes. Safari: > target.style.cssText < "font-family: inherit, serif;" > window.getComputedStyle(target).fontFamily < "inherit, serif" Firefox, Chrome: target.style.cssText 'font-family: "inherit", "serif";' window.getComputedStyle(target).fontFamily '"inherit", "serif"' Same thing is happening for a font-name Safari > target.style['font-family'] = '"Helvetica"' < "\"Helvetica\"" > target.style.cssText < "font-family: Helvetica;" > window.getComputedStyle(target).fontFamily < "Helvetica" Firefox: target.style['font-family'] = '"Helvetica"' '"Helvetica"' target.style.cssText 'font-family: "Helvetica";' window.getComputedStyle(target).fontFamily '"Helvetica"' 2023577 1 webkit-bug-importer 2024-03-24 21:58:11 -0700 <rdar://problem/125334960> 2192931 2 vitor.roriz 2026-03-23 16:46:36 -0700 Pull request: https://github.com/WebKit/WebKit/pull/61204 2193730 3 ews-feeder 2026-03-25 20:19:50 -0700 Committed 309959@main (d8a232e3b659): <https://commits.webkit.org/309959@main> Reviewed commits have been landed.
