RN: White screen potentially related to russian translation


QA notes: Reproduced on iOS as well (removed "Android" from ticket title). Only reproduces when Account Settings > Display > Language is set to Russian (does not repro on English or Ukrainian).

Reproduces on both 5.6 and 5.8 server on:

  • v1.15.2 (170)

  • v1.15.1 (166)

  • v1.15.0 (163)

Does not reproduce on either 5.6 or 5.8 server on:

  • v1.14.0 (158)

Added repro steps in the QA steps section, using another previous report as a starting point: https://github.com/mattermost/mattermost-mobile/issues/2482. But does not appear to require a new channel. Servers it repro'ed on: ci-linux-mysql-prev (5.6), ci-linux-postgres (5.8), ci-linux-mysql (5.8).

Original description:
Not clear on exact repro but seems to be issues the app hanging and showing a white screen when using Russian translation on Android.

I've asked QA to look into it as well for more specific repro.

QA Test Steps

1. Log in to an account using browser or desktop app, set Account Settings > Display > Language to Russian
2. Log in to that same account on RN Android or iOS
3. Repeatedly open channel drawer and switch channels (in my testing, does not appear to matter which channels, whether they're new, whether display name is in Cyrillic).

NOTE: This report believes it is actually the Off-Topic channel causing the issue: https://forum.mattermost.org/t/application-hangs-after-visiting-off-topic-ios-and-android/6602/5 (I do know in my screen record it was Off-Topic when the issue happened, but I thought that was inconsistent)

Observed: After anywhere from 3 to 10 or so channel switches, screen shows blank. To get it back working, user must change language away from Russian, then restart RN app

Expected: No blank screen appears after switching channels
