Thanks !

@EvanBacon Sorry to bother you, but could you check this PR really quick ? I feel like this issue is impacting a lot of other librairies, and I need it tbh :D

Thanks !

Yeah, it's weird that they don't fix it themselves or approve this pull request :/

Hey, thanks for the PR. Everything looks good, but it seems that I cannot push to your master branch to fix conflicts. I'll merge this PR when conflicts will be resolved.

I’m away from a computer until next week. I’m glad this issue is finally getting traction but this PR has been out forever...

[jlkalberer]

I'll have a fix for this today with iOS testing. Be ready to merge :D

[jlkalberer]

I rebased my changes on top of this branch and have tested things again. I've updated the original PR with the new test plan.
