Missing 'viewport' problem was not shown near <meta> element
Is your feature request related to a problem? Please describe.
My html page had a <meta> element in <head>, but the problem for a missing 'viewport' wasn't shown inline. Instead, it was shown at the root <!DOCTYPE> element.
Describe the solution you'd like:
I'd like to see problem next to the <meta> element, similar to the '<html> element must have a lang attribute...' problem. See both attached images to compare the difference.
Describe alternatives you've considered:
Additional context:

Wouldn't the
element make more sense? Meta needs to be a child of that one.
Yeah, I think pointing this at the <head> element (if present) would make more sense, the <html> element otherwise, and finally falling back to the start of the document if no <head> / <html> element is present.
