This looks good, so going to approve and merge. For manual QA, I don't see any issues but I'd only noticed this bug when running the pex file during the bug bash, not when running the dev server. I can download that later today or tomorrow and confirm the fix is working as expected.

We can give it a go now! 🙂 (cc @pcenov)

Looks good to me as well - I'm not seeing any suggestions that Kolibri is disconnecting.
At the same time I noticed that when I click the View more option while viewing the page in mobile view there is an error in the console: GET http://127.0.0.1:8080/en/learn/[object%20Object] 404 (Not Found)

@pcenov - I was looking at this today and so far haven't been able to replicate it, so I want to double check that I'm trying the same scenario. I am on the home page as a logged in user, who is not enrolled in any classes. I am clicking "view more" under the "Continue learning on your own" header. Is this what you were testing? If not, can you let me know what I should try instead? Thank you!!

[pcenov]

@marcellamaki to replicate this one you have to:

1. Go to the Library page
2. Filter by some criteria, for example Language: English
3. Select the View as list option for the search results
4. Scroll down and click the View more button
   I just mentioned it above as an indirect observation for a possible issue - let me know if I should report it separately.

[marcellamaki]

Thank you @pcenov -- I will try that! And no need to report is separately - I'll take a little time today to investigate and address
