Load attached testcase, and look at the alert() that appears. EXPECTED RESULTS: alert should say PASS (i.e. `document.styleSheets.length` should be 4) ACTUAL RESULTS: alert says FAIL, and reports that document.styleSheets.length is in fact 2. Firefox and Chromium both give expected results. Safari 14 gives actual results. 1756643 1 dholbert 2021-05-04 13:07:23 -0700 The relevant spec text here is: https://drafts.csswg.org/cssom/#add-a-css-style-sheet Note that the last two stylesheets here should be be flagged as *disabled* (which is why they don't render in any browser; i.e. it's why the document renders as cyan instead of red or pink). Chrome doesn't set the disabled flag properly, which is a bug[1], but it does treat them as disabled from a rendering perspective and it does correctly add it to the list of stylesheets. This WebKit bug here is about these sheets being missing from the document.styleSheets list.

Hmm - I'm not 100% sure, but it looks like it very well could be.

Just wanted to share updated testing result.
