Awaited localized reads resolve in the project locale while a startup selector's "PrepareAsync" is still running

How to reproduce:
1. Open the attached project "LocalizationAET"
2. Go to Localization Repro -> Run editor cases
3. In the Console, observe the messages with the [Case 2] tag

Expected results: The awaited read waits for initialization and returns "Bonjour", the locale the startup selector chose
Actual results: The awaited read returns immediately with "Hello", the project locale, and only a later read returns "Bonjour"
