@Zeyber so far so good, the only thing that I noticed is that two Tab key strokes are needed to get into the content panel, auditors have complained about that in other components.
Is it possible to go to the first option in the panel on the first stroke but without losing the items count for the group? So, perhaps move the aria-label with the group's items count to the collapsible button.
