Fix declaration-block-no-redundant-longhand-properties invalid background autofix with background-size - #9364

…kground` autofix with `background-size` The fixer combined background longhands by space-joining the values in property order. With background-size present that emits an invalid declaration, since the size must follow the position separated by a slash (and per-layer for comma lists). Skip the fix in that case so the rule still reports but no longer rewrites valid CSS into invalid CSS.

Thanks for the PR.
Reproduced in the issue in the demo.
Updating the autofixer to use / and work correctly is more effort, so this temporary fix to avoid autofixing invalid CSS feels like an appropriate step.
I've requested two changes.

Let's short-circuit the prefix compute.

Let's update the comment to leave a TODO and explain the temporary fix.

Should we add an issue for it? |
Only compute the vendor prefix when the shorthand is `background`, and reword the comment as a TODO pointing at the proper slash-separated fix.

This plugin includes two new parsers: `yuku` (JavaScript syntax) and `yuku-ts` (TypeScript syntax). **To use this plugin:** 1. Install the plugin: ```bash yarn add --dev prettier @​prettier/plugin-yuku ``` 2. Add it to your `.prettierrc`: ```yaml plugins: - "@​prettier/plugin-yuku" ``` Due to package size limitations, this plugin is not bundled with the main prettier package and must be installed separately.

Which issue, if any, is this issue related to?
None open. Issue #7232 added
ignoreLonghandspartly so thatbackground-sizecould be excluded from this fixer; this addresses the same underlying problem in the default behaviour.Is there anything in the PR that needs further explanation?
The problem
When all of the
backgroundlonghands are present, the autofix produces an invalidbackgrounddeclaration ifbackground-sizeis among them:is fixed to
In the shorthand,
background-sizemay only appear immediately afterbackground-position, separated by a/. Here the size ends up next to the image with no slash, so the value doesn't parse and a browser drops the whole declaration. The correct form would bebackground: url(x) 0 0 / contain .... With comma-separated layers it's worse — the longhand lists just get space-joined and the layer grouping is lost.The fix
The default resolver just space-joins the longhand values in property order, which can't express the
position / sizeform. Rather than try to reconstruct that (single- and multi-layer), I make the resolver bail out of fixing whenbackground-sizeis present, the same waygrid-templatealready bails onrepeat(). The rule still reportsExpected shorthand property "background"; it just no longer rewrites valid CSS into invalid CSS. Users who do want the combine can still opt the size out viaignoreLonghands: ["background-size"], which produces a valid shorthand as before.Did you add or update tests?
Yes. Added reject cases (single-layer and comma-separated multi-layer) asserting the rule reports but leaves the CSS unchanged (
unfixable). They fail onmain(where the bad fix is applied) and pass with this change. The existingignoreLonghandstest still passes. Rule tests (104), ESLint, Prettier and remark pass locally.Have you successfully run tests with your changes locally?
Yes.
