1878679 - Use of async in TranslationsMiddleware

Status: NEW

Description

[Olivia Hall [:olivia]]

This bug is to research using async within requestSupportedLanguages as a precaution against unintentionally blocking the main thread. This might also be a good place to better document the interplay between GeckoView and Android Components in terms of applicable threads items can be called on. See bug 1877588 for more details.

On the GeckoView side, it is believed requestSupportedLanguages is not blocking and running on the main Gecko thread. A JS Promise is resolved to a GeckoResult. This bug is more precautionary than a known issue.
