Could you please advise on what to do with test coverage? Before my pull request, the file frontend-app-account/src/account-settings/EditableSelectField.jsx had no test coverage at all. I added tests for this file, but the coverage actually decreased.

@DmytroAlipov take a look at the indirect changes in CodeCov:
https://app.codecov.io/gh/openedx/frontend-app-account/pull/896/indirect-changes

There are two codecovs checks:

• codecov/project Failing after 1s — 46.50% (-0.13%) compared to ...
• codecov/patch — 100.00% of diff hit (target 46.63%)

We can see your changes are 100% that is awesome, but somehow the project declines by tiny 0.13 (annoying I know) workaround add test to anything else in the project to help increase coverage and call it a day

@heldersepu done!
