Misusage of aria-expanded in new plugin directory

[joedolson]

The aria-expanded attribute is attached to the container div in the new directory; but the aria-expanded attribute needs to be on the controller, not on the controlled container. The attribute indicates whether the button you've focused on controls an element that's currently expanded or currently collapsed.

The aria-expanded attribute needs to be moved from the container div elements to the button in question.

To clarify: is this referring to a detail page for a plugin, not the plugin directory home page? Is this also in reference specifically to the Read More buttons on those detail pages, rather than the nav section (which seems to use aria-expanded correctly)?

In 4464:

Correct usage of aria-expanded attribute.

It belongs on the toggeling element, not the element that is being expanded.

Fixes #2291.
