166782 2017-01-06 15:48:51 -0800 WebKit implements "word-wrap" as a weird sort of alias which shows up in serializations alongside its alias-target 2022-05-12 08:37:32 -0700 1 1 1 Unclassified WebKit CSS Safari 10 Unspecified Unspecified RESOLVED FIXED https://bugs.chromium.org/p/chromium/issues/detail?id=679068 InRadar, WPTImpact P2 Normal --- 239579 240341 1 dholbert ntim ntim obrufau webkit-bug-importer oldest_to_newest 1264556 0 dholbert 2017-01-06 15:48:51 -0800 STR: (1) Visit https://jsfiddle.net/5esq3oc8/ (2) Inspect the serialization of the div's CSS rule for its "style" attribute. (Shown in an alert dialog) EXPECTED RESULTS: "word-wrap" should not appear (since it's an alias for "overflow-wrap"). ACTUAL RESULTS: "word-wrap" and "overflow-wrap" *BOTH* appear, despite the fact that the former is an alias for the latter! In contrast, the other alias included in this testcase (-webkit-align-items) does not show up -- for that one, only the main property appears in the serialization. NOTES: * This bug affects Chrome/Blink as well; the Blink instance of this bug report is https://bugs.chromium.org/p/chromium/issues/detail?id=679068 * The spec text here is pretty hand-wavy, and Manish filed https://github.com/w3c/csswg-drafts/issues/866 on that. Right now it says "UAs must treat word-wrap as an alternate name for the overflow-wrap property, as if it were a shorthand of overflow-wrap." https://drafts.csswg.org/css-text-3/#propdef-word-wrap * That spec text seems to be basically describing the concept of an alias ("an alternate name", "as if it were a shorthand" -- notably *not* saying that it's *actually* a shorthand). So, WebKit should be doing its standard legacy aliasing thing here, just like it does for -webkit-align-items. I'm not sure why it has different behavior for this one special property. Probably some weird historical cruft, I'm guessing, which can be cleaned up now? :) I tested in Safari 10 on sierra and got ACTUAL RESULTS. Chrome 57 dev edition also gives ACTUAL RESULTS. Firefox Nightly 53 gives EXPECTED RESULTS. Edge 14 gives an entirely different behavior because they don't yet support "overflow-wrap" (https://wpdev.uservoice.com/forums/257854-microsoft-edge-developer/suggestions/6524680-update-word-wrap-to-overflow-wrap ) 1864836 1 ntim 2022-04-27 10:12:29 -0700 Pull Request: https://github.com/WebKit/WebKit/pull/411 1864868 2 ews-feeder 2022-04-27 11:56:52 -0700 Committed r293521 (250052@main): <https://commits.webkit.org/250052@main> Reviewed commits have been landed.
