fix(NcActions): intercept into current focus trap stack

[ShGKme]

☑️ Resolves

• Resolves: NcActions doesn't work inside an element with a focus trap in a general case #4910

When the component has its own focus trap, then it is managed by global trap stack by focus-trap.

However if the component has no focus trap and is used inside another focus trap - there is an issue. By default popover content is rendered in body or other container, which is likely outside the current focus trap containers. It results in broken behavior from focus-trap.

We need to pause all the focus traps for opening popover and then unpause them back after closing.

Focus trap still works.

Supports multi-level focus traps (header menu focus trap inside sidebar trap):

Could be risky. A good review is appreciated 👀

sequence is unfortunately not fully correct ;( -> both directions: forwards and backwards

Doesn't work on Photos well ;( -> seems to be a regression, works on try.extcloud

I cannot reproduce. The gif looks exactly how it was before this PR. Could you check that npm link and rebuild was successful?

On what page what it is recorded?

The issue happens when there are any inline actions. They are also counted in menu actions when determining what kind of menu we have.

Preparing another PR.
