Tabs ADA Title II non-compliant in horizontal orientation

Describe the issue

Per WAI-ARIA tabs pattern, the up and down arrow keys should not be listened for in horizontal orientation. The Bootstrap example shows it being listened for. The minified bootstrap bundle shows it being listened for. I am unable to override it in my own code, leaving the websites I work on ADA Title II non-compliant where Tabs are used.

I have verified that nothing in my own code is listening for the ArrowDown nor ArrowUp keydown event.

Issue occurs in all desktop browsers.

Reduced test cases

See the Bootstrap example.

What operating system(s) are you seeing the problem on?

Windows

What browser(s) are you seeing the problem on?

Chrome

What version of Bootstrap are you using?

v5.3.8

Start with the Bootstrap navs and tabs JavaScript behavior example and compare it with the minified Bootstrap bundle, focusing on ArrowUp and ArrowDown keydown handling in horizontal orientation. Verify the behavior against the WAI-ARIA tabs pattern and test the example in desktop browsers. Done means horizontal tabs no longer listen for those arrow keys while the documented tab behavior remains functional.
