Bad Russian font weight

[nikstar]

After recent update (ver. 66) Russian symbols are displayed with incorrect weight across the app. It is most noticable when a string contains both Latin and Cyrillic symbols. 

Cyrillic symbols have normal weight where bold weight is expected. This looks really bad, I had to downgrade to a previous version 

Attached: Compare ver. 65 (ok) vs ver. 66 (bad, same on 68 beta) on Android 10

Hopefully this will be fixed soon.
