[ML] Link to ml app goes through several redirects before getting to app

[kindsun]

Kibana version:

7.14

Describe the bug:

Clicking on the ML app link sometimes goes through several redirects before landing on a blank page, but not always. Sometimes it gets the app correctly but a user still can't navigate back correctly (maybe a redirect that should replace instead of adding to history?). Seems like there might be a race condition (not entirely sure how to consistently trigger) but also minimally some router behavior that could be tweaked.

Steps to reproduce:

1. Go to Kibana overview page
2. Click machine learning app card

I've been unable to reproduce the first scenario in this issue.
I've tried master, 7.14.0 local and 7.14.0 cloud.
I've also tried various degrees of network throttling.

Thanks for checking @jgowdyelastic. If I can repro it I'll try to better capture the circumstances. As it stands, I can't repeat that behavior today 🤷‍♂️. Maybe scenario 2 will be the only real takeaway from this issue, which thankfully isn't too critical.

Actually @jgowdyelastic wrt the 1st scenario, I got it again while running tests in Firefox. I tested it in parallel in Chrome and it worked fine even though I saw the error in Chrome before when I first reported this. It might be worth a local test in Firefox if you get a chance.

I got the following output in Firefox's console:

Reporting application usage for ml, / kbn-ui-shared-deps.js:456:425521
Reporting application usage for ml, /overview kbn-ui-shared-deps.js:456:425521

.... <Same lines above repeat 10+ times before hitting the following error>
Too many calls to Location or History APIs within a short timeframe. history.js:380

So it gets stuck in a redirect loop going from / -> /overview -> /datavisualizer -> / -> ...

Anyway, curious to see if you see it in Firefox. If not, we can just consider it logged and see if anyone else sees something similar down the road!

@aaronjcaldwell thanks for the additional information, i'm still not able to reproduce on master or 7.14 when using Firefox.
Can you confirm that you're using a basic license, as it appears that way from the screenshots.

[kindsun]

@jgowdyelastic Yes, can confirm I was using a basic license in all attempts.

Unable to reproduce this on 7.15.0 (local install). Tried using basic and trial license, on Chrome and Firefox. Removing 7.15.0 label, but leaving issue open to track if anyone else sees something similar.
