1820252 - Add an IntersectionObserver to prioritize translations

Status: NEW

(Firefox :: Translations, enhancement, P3)

Description

[Greg Tatum [:gregtatum]]

Translations are CPU-intensive and take time. This means that they can be bad for power usage and battery life. The current implementation manually checks the bounding client rect. Rather than doing this we should use an IntersectionObserver to decide what to translate. This observer should continuously adjust the WorkQueue so that only the necessary translations are done.

This should cut down on a very large percentage of translations that a user will never see.

Maybe this will help improve performance when translating Wikipedia popups (see bug 1845776).
