Some macros erroneously report case mismatch

[bsmth]

What information was incorrect, unhelpful, or incomplete?

There are some usages of macros that are reported as flaws, for example:

{{htmlelement("Heading_Elements", "h1")}}

Reports

/en-US/docs/Web/HTML/Element/heading_elements is ill cased

and:

Macro produces link /en-US/docs/Web/HTML/Element/heading_elements which is a redirect

Although the document is https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Heading_Elements

https://github.com/mdn/content/blob/32a1f3fd761455da4ac94e89e50efb07fb322b76/files/en-us/web/html/element/heading_elements/index.md?plain=1#L3

What did you expect to see?

No flaw(s) reported in this case.

Do you have any supporting links, references, or citations?

Do you have anything more you want to share?

Reproducible with:

Something {{htmlelement("Heading_Elements", "h1")}} here

The following appears to work as expected:

{{glossary("rate_limit", "thing")}}

In that it's reporting no flaws when case is correct, and a flaw when there's a case mismatch for https://developer.mozilla.org/en-US/docs/Glossary/Rate_limit
