Adding a bit more context, as I didn't understand the first few times I read this.
This is regarding the horizontal (dropdown) menu
The WCAG criteria referenced is 1.4.13 "Content on Hover or Focus" https://www.w3.org/WAI/WCAG21/Understanding/content-on-hover-or-focus.html which states that:
Where receiving and then removing pointer hover or keyboard focus triggers additional content to become visible and then hidden, the following are true:
Dismissible
A mechanism is available to dismiss the additional content without moving pointer hover or keyboard focus, unless the additional content communicates an input error or does not obscure or replace other content;
Hoverable
If pointer hover can trigger the additional content, then the pointer can be moved over the additional content without the additional content disappearing;
Persistent
The additional content remains visible until the hover or focus trigger is removed, the user dismisses it, or its information is no longer valid.
The issue here is that the submenu appears on hover and focus, and you cannot dismiss it. Closing the submenu with the ESC key would resolve this issue.
Patch #7 works for me too. :)
Thanks in advance to the most awesome maintainers.
