794245 - Putting an app in the background before gecko is loaded can leave the splash screen showing forever

Status: RESOLVED WORKSFORME

(Firefox for Android Graveyard :: Web Apps (PWAs), defect, P2)

Description

[Wesley Johnston (:wesj)]

1.) Start the app
2.) While Gecko is still loading, hit home
3.) Return to the app

Result: Splashscreen shows forever. I think the page actually loads, but we never get the DOMContentLoaded event in Java and never hide the splashscreen. Not sure why the events aren't sent. Maybe some optimization for when we're in the background?

Noming mainly cause I'm a bit nervous if this actually happens, which is certainly possible.

mfinkle: I think we can do a simple workaround here and just hide the splashscreen whenever we get an onPause event. I'd love to understand what's going wrong, but I spent awhile on it before and couldn't pin down what was happening.

Bumping to P2 since this wouldn't block, but we probably should be tracking this one.

Re-testing this, this is WFM. Wes, re-open if you can reproduce.
