Why

4.1.0 breaks most of the CSS in about 7 stylesheets on every site, and 28 on admin.stores.com. These are the pages/*, links/* and analytics stylesheets, plus everything that includes the SDK's Bootstrap.

The cause is an old bug in electricity's url(...) rewriting that 4.1.0 made visible:

1. Bootstrap's navbar toggler uses a quoted data URI that contains rgba(0, 0, 0, 0.5).
2. The rewriter stopped at the first ), found no file at that "path", and wrote the URL back without its opening ", leaving a stray " behind.
3. The browser reads that stray " as the start of a string, and a string runs until the next line break.
   • In readable or UglifyCSS output, that cost one rule.
   • In 4.1.0's compressed output, the whole file is one line, so the string runs to the end and the browser drops every rule after it.

Rules the browser kept, measured by loading the files in Chrome:

Stylesheet	Readable	4.0.0 (UglifyCSS)	4.1.0	This fix
morningsave.com pages/index.css	5,756	5,756	616	5,755
meh.com links/list.css	2,515	2,515	972	2,514
admin.stores.com upload/index.css	2,112	—	1,610	2,111

The one-rule difference left with the fix is an empty .bootstrap { } block, which compressed output drops.

This is what fails admin.stores.com's /upload accessibility test on main. Its .ext-chip rule comes after the toggler, so the labels rendered unstyled. The same commit with electricity 4.0.0 passes.

What changed

• lib/processor.js: a quoted URL now ends at its matching closing quote (url\((['"]?)(.*?)\1\)), and a URL that doesn't match a file is left exactly as written instead of losing its quotes.
• A new test compiles a .scss fixture with such a data URI and checks that the URL stays whole. It fails on 4.1.0 and passes with this fix.
• Version 4.1.1 and a changelog entry.

Sites depend on ~4.1.0, so they pick up 4.1.1 on their next CI run or deploy without any package bumps.

Testing

• npm test: 66 of 66 pass, and npx eslint . is clean.
• Compiled every stylesheet that had a broken url(...) on all 12 sites (126 files) with this fix and loaded each in Chrome in both compressed and readable form. All of them keep every rule except the empty .bootstrap { } block, and no unquoted URL containing a quote is left.
