From what I understood in my research, some Intent calls made for a system web browser are considered by lint to launch JetpackConnectionResultActivity, which only cares about wordpress://jetpack-connection?reason={error} type of links (not https). I'd appreciate a second check if this make sense. I'm also not sure what's the prefered solution - suppressing, or maybe there's something better like communicating to Intents that it should point to external components only?
