[BUG] Crash when presenting UIPopoverPresentationController on an iPad

[nalexn]

Summary

Stripe identity verification SDK crashes for iPads with the following message:

NSGenericException · Your application has presented a UIAlertController (<UIAlertController: 0x10d0a7000>) of style UIAlertControllerStyleActionSheet from StripeIdentity.IdentityFlowNavigationController (<StripeIdentity.IdentityFlowNavigationController: 0x10d08da00>). The modalPresentationStyle of a UIAlertController with this style is UIModalPresentationPopover. You must provide location information for this popover through the alert controller's popoverPresentationController. You must provide either a sourceView and sourceRect or a barButtonItem. If this information is not known when you present the alert controller, you may provide it in the UIPopoverPresentationControllerDelegate method -prepareForPopoverPresentation.
