If this issue only occurs in one browser, which browser is a problem?

Describe the Bug

The Audit tool in the toolbar reports an accessibility issue, "Missing content" for anchors and headings in closed details elements unless the elements have aria-labels explicitly set, or the details element includes the open attribute. The issue persists upon manually opening the details element via clicking the summary.

This was replicated in StackBlitz on Node 20.19.1 but the same behavior occurs on my machine with Node 22.12.0 as required.

What's the expected result?

Since inner text is valid, I believe the audit should pass.

To my knowledge, accessibility is affected when elements have explicitly set display to none, visibility to hidden, or use the aria-hidden="true" attribute. The details element does none of these by default from what I can tell.

This might need better research - I'm not totally up to date with accessibility regarding detail/summary blocks. I couldn't find anything specific in the spec or on MDN.
