Android RTL support is affected by the flavor's resConfigs

Question

Following some recent changes to one of our flavor regarding supported languages, we noticed it somehow also affects the RLT support.

flavorA {
    resConfigs 'en', 'pt', 'fr', 'es', 'de'
}

flavorB {
    resConfigs 'en'
}

With the configuration, when the device language is Arabic or any other RTL language:

• A content is locked Left To Right (LTR)
• B content is Right To Left (RTL)

Now if I am updating flavorA to resConfigs 'en'. It now supports RTL again

Looking at the documentation for resConfigs, I am not seeing anything about affecting RTL capacities: https://developer.android.com/guide/topics/resources/multilingual-support#specify-the-languages-your-app-supports

How can I get RTL to be supported by A?
