css.selectors.highlight - stroke not supported in any major browser, text-shadow not supported in Safari

[flying-sheep]

What type of issue is this?

Incorrect support data (example: BrowserX says "86" but support was added in "40")

What information was incorrect, unhelpful, or incomplete?

The “allowable properties” section of the page lists among others text-shadow and -webkit-stroke-*

It correctly reports that firefox doesn’t support text-shadow, but doesn’t mention that no major browser supports -webkit-stroke-*.

What browsers does this problem apply to, if applicable?

I tested it on:

• Safari 26.2 (21623.1.14.11.9)
  • no support for text-shadow or -webkit-stroke-*
• Firefox 147.0.1
  • no support for text-shadow (already known) or -webkit-stroke-*
• Chrome 143.0.7499.194
  • no support for -webkit-stroke-*

What did you expect to see?

The 3 browsers’ support matching the data.

Did you test this? If so, how?

Open this demo with any browser, check what works in the right column of the table.

doesn’t mention that no major browser supports -webkit-stroke-*.

This looks primarily like a content issue, because the spec does not seem to mention the -webkit- prefixed properties.

Please note that BCD currently doesn't allow features without implementation in any browser (unless there is intent to implement), so if the BCD table had rows for the different properties, it wouldn't have rows for the unsupported ones. Furthermore the BCD collector has a single test case for ::highlight, i.e. no test cases for the individual allowable CSS properties.

Closing as won't fix, I will open a content issue.
