Uses deprecated APIs 1 warning found and DOM size

[timholz]

Now and again the test issues warnings like:

Uses deprecated APIs 1 warning found
Deprecated APIs will eventually be removed from the browser. Learn more about deprecated APIs.
Found an h1 tag within an article, aside, nav, or section which does not have a specified font-size. The size of this heading text will be changing in this browser in the near future. See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Heading_Elements#specifying_a_uniform_font_size_for_h1 for more information.

This is not always reported. It just occasionally pops up. I examined the html and the css. The font-size is specified.

I learned, that the threshold for a large DOM is 1500 elements. The test reports with a DOM size of 277 elements, that it is already too large. Why is that?

Can you provide a URL?

[timholz]

Since the results are quite arbitrary and the test’s analysis is incongruent with the mark up and css, providing a URL does not make sense. Sometimes the mentioned warnings pop up and then again they do not appear at all. You could probably test 10 times and everything is ok and then with the 11th attempt the warnings show again. I think this test is rather unreliable. Is it AI driven?

[connorjclark]

There's no AI.

For deprecation warnings, we are only surfacing what Chrome emits. If there's an issue with a particular deprecation warning you will need to raise it here: http://crbug.com/

For the Dom size issue, we have two audits currently about that, so I need to know what you're referring to. But I think you are referring to the new "insight" audit, but I'm not sure. We have improved it recently. What version of Lighthouse are you using?

[timholz]

Thanks for your concise answer. Yes, i am referring to the new "insight" audit. Regarding the lighthouse version, except for «Desktopemulation with Lighthouse 12.7.1» i can find no other indication.
