  FKA: The auto-generated label in a <details> element without a <summary> is not keyboard accessible
https://bugs.webkit.org/show_bug.cgi?id=78499

Reviewed by Tim Nguyen.

The bug was caused by the summary element in details element's shadow tree getting skipped during
sequential focus navigation because it has custom focus logic. Fixed the bug by removing this.

The test was originally written by Arko Saha.
