CardField crash the app with EXC_BAD_ACCESS on iOS 13.*

See original GitHub issue

Describe the bug <CardField /> cause a crash if field is not completed when focused previously and got unmounted later on. Happens only on iOS 12

To Reproduce Steps to reproduce the behavior:

Create navigation stack with react-navigation
Add <CardField /> component
Focus on CardField without enter anything
Go back navigation.goBack
Navigate to the screen with CardField again
Try to focus CardField
App crashes with EXC_BAD_ACCESS

I’m expecting this to crash too if <CardField /> got unmounted and mounted again on the same screen, but have not tried it yet.

Expected behavior App not crashing

@aganov we are aware of this issue and where it comes from, unfortunately we cannot re-implement it because of PCI compliance. We’re in the middle of looking for solution to correct card field deallocation. Thank you for providing such precise dubugging results.

We’ve created example app https://github.com/aganov/stripe-rn-ca-mask-crash containing just react-navigation and stripe-react-native https://github.com/aganov/stripe-rn-ca-mask-crash/blob/master/App.js it crashes with EXC_BAD_ACCESS on CA::Layer::mask() every time you go back from the screen containing <CardField /> Please note that crash happens only on iOS 13.* like our production app.
