SC 2.1.2: Leave, but to where?

for

A project wants to include a navigational menubar. Searching for best
practices I found a WAI example:


<https://www.w3.org/TR/wai-aria-practices/examples/menubar/menubar-1/menubar
-1.html#ex_label>
https://www.w3.org/TR/wai-aria-practices/examples/menubar/menubar-1/menubar-
1.html#ex_label



The problem: I cannot leave the menu with arrow keys. Pressing arrow-right
holds me in the carousel of elements in the menubar.

By pressing tab, I can leave the navigational component, but I land
somewhere on the next focusable element. This way I bypass the content
between.



Is this a violation of SC 2.1.2?

How should we solve this issue? Give the first element behind the navigation
in the DOM a tabindex?



As a SR user I don't like menus for navigations at all, but this is because
I never found an example causing no problems. I tested the example above
with jaws 2020 Firefox, chrome, and edge. None supported all available
aria-attributes. And when the mouse occasionally was in the wrong place,
arrow-right did not move the focus but started spelling a word letter by
letter. And I use the mouse, when I work with magnification.



Thanks for ideas!
