Store switching is occasionally not working

[sigismund]

Preconditions

1. Magento 2.2
2. 3 different stores (sl, en, hr)

Steps to reproduce

1. Enabled "Add Store Code to Urls"
2. (Not sure which other options could affect this behavior )

Expected result

1. When changing language in dropdown, the website should change

Actual result

1. If I try to switch from Slovenian product to English version of it, request is sent from /sl/testing-example to /en/testing-example(example). After that /en/testing-example redirects (302) back to /sl/testing-example. I tried changing slug of english product and in some cases I even got 404 response.

PR #11337 should solve this problem @vkublytskyi

@thiagolima-bm, yes this issue already fixed and will be released with next 2.2.x patch release

[sigismund]

Is this supposed to be included in Magento 2.2.1?
