Management app shows the sections that are not allowed by the current user capabilities

[azasypkin]

Kibana version: 7.10.0+

Describe the bug:

While investigating flaky tests in #90576 we noticed that sometimes Management app displays sections that it shouldn't and full page refresh fixes that.

Steps to reproduce:

1. Prepare two users: user A (with superuser role) and user B (with kibana_admin role).
2. Log in as user A and navigate to the Stack Management, and observe Ingest section
3. Log out and re-login as user B (without refreshing the page)
4. Navigate to the Stack Management and observe Ingest section. It shouldn't be shown, check the latest /capabilities response in the Dev Tools and make sure that all "apps" are set to false for ingest.
5. Refresh the page, Ingest section is no longer displayed.

Screenshots (if relevant): (Kibana 7.11 in Cloud)

Any additional context:

It's not immediately clear where the issue is exactly, but I'd like to make sure that Management app correctly analyzes user capabilities first. I noticed that you check capabilities in start, but it may become a problem in the future when we eliminate full page refresh on login/logout steps.

Correction, @legrego pointed out that it's known limitation and only needs to be handled once we have a solution for #59377.

It looks like there are a couple of other recent failures that look very similar to the ones described in this issue:
#91330
#91305
#91262

I wonder if #90782 didn't fully address the race condition.

I'll reopen this, but feel free to close in case I read new failures wrong

I also believe there are several more related ones:
#91028
#91442
#91331

What changed recently to introduce all of this flakiness? This was solid when first introduced in 7.10 🙁
