• Button + manual focus - doesn't move focus (both general and screen reader)
• Link + prevent + manual focus - doesn't move focus (both general and screen reader)
• Link with native behavior - focus is moved, but with a very weird behavior.
  It is moved though other elements, e.g. skip links of table header. And I cannot understand why...

For example, on this video, after click the screen reader focus is successfully moved on the header. However, it made many steps and went through other elements, like 5th user's action menu button (yellow square).

I tried to disable the focus trap, remove debounce unfocus, play with the link and nothing helped.

If you don't have any ideas here, I'd propose to disable default link behavior for now with .prevent and fix it later.

disable default link behavior for now with .prevent

Following behavior will take place: link will be semantic link but will work as a button. That means focus will stay on links and strange focus behavior will be prohibited.

Let's do that! -> Right/perfect focus isn't so important as odd screen reader behavior

• It is moved though other elements

Maybe because it is handled like navigation -> reset to tabstop 0 and then move to ID?

I tried similar navigation on MDN and it worked fine...
