Description

Follow-up to #64351

Under a viewport height of 550 pixels, the metaboxes area container now turns into a <details> element. See

As reported on #64351 (comment) by @joedolson a <details> element isn't ideal in this case. Basically it should not be used for sections of content that need a heading to identify the section. Also, it should not be used for accordion-like UIs. Rather, an expandable section with a heading 'Meta Boxe' should be used instead.

Step-by-step reproduction instructions

• Activate a plugin that adds a metabox e.g. Yoast SEO.
• Edit a post.
• Emulate a viewport height that is smaller than 550 pixels.
• Observe the metaboxes area turns into a <details> element.
