### What?
The `locale selector` in the version comparison view shows all locales
on first load. It does not accomodate the `filterAvailableLocales`
option and shows locales which should be filtered.
### How?
Pass the initial locales through the `filterAvailableLocales` function.
Closes#11408
#### Testing
Use test suite `localization` and the `localized-drafts` collection.
Test added to `test/localization/e2e`.
