The first synchronous "GetLocalizedString" returns the project locale even though initialization completes inside that same call and selects the startup locale

How to reproduce:
1. Open the attached project "LocalizationAET"
2. Build and Run the project
3. Go to project root -> ReproResults -> case3.txt
4. Observe the results

Expected results: The first synchronous read returns "Bonjour", the locale the startup selector chose
Actual results: The first synchronous read returns "Hello", the project locale, while "SelectedLocale" reads "fr" immediately after the same call

Reproducible with: 6000.7.0a6

Reproducible on: macOS Tahoe 26 (M1)
Not reproducible on: No other environment tested

Note: Only reproducible in a Player, because the path depends on Application.isPlaying
