From original repository:

     Verified Compliance: Passes all 9k+ tests in the official html5lib-tests suite (used by browser vendors).
Yes, browsers do you use it. But they handle a lot of stuff differently.

    selectolax  68%  No  Very Fast  CSS selectors C-based (Lexbor). Very fast but less compliant.
The original author compares selectolax to html5lib-tests, but the reality is that when you compare selectolax to Chrome output, you get 90%+.

One of the tests:

  INPUT: <svg><foreignObject></foreignObject><title></svg>foo
It fails for selectolax:

  Expected:
  | <html>
  |   <head>
  |   <body>
  |     <svg svg>
  |       <svg foreignObject>
  |       <svg title>
  |     "foo"
  Actual:
  | <html>
  |   <head>
  |   <body>
  |     <svg>
  |       <foreignObject>
  |       <title>
  |     "foo"
But you get this in Chrome and selectolax:

    <html><head></head><body><svg><foreignObject></foreignObject><title></title></svg>foo
    </body></html>

This is a namespacing test. The reason the tag is <svg title> is that the parser is handling the title tag as the svg version of it. SVG has other handling rules, so unless the parser knows that it won't work right. I would be interesting to run the tests against Chrome as well!

You are also looking at the test format of the tag, when serialized to HTML the svg prefixes will disappear.
