Bug Report

When presenting the default lock screen on iOS 13 on an iPhone app that uses the multi-window API, only a black screen displays and is not animated. This may be related to #1430.

Reproduction Steps

1. Set up a new example app through Xcode that uses the default multi-window API.
2. For the lock screen configuration, use the .enabled() default configuration
3. Alter the driver distraction state on the module to toggle the lock screen

Expected Behavior

Equivalent behavior to iOS 12

Observed Behavior

A black screen appears / disappears over the existing screen without animation

OS & Version Information

• iOS Version: 13.1.3
• SDL iOS Version: 6.4.0
• Testing Against: Sync Gen 3 (but this does not matter)

There are two points.
You only correct one. Could you modify it on line 50 also?

This is my mistake. I'll confirm it.
