reproduction #1637

[hannojg]

Description

Provides a reproduction case for:

• [Ios] app lags/stutters while navigating to a new screen with auto focused text input #1637

I am currently running an investigation / fix for that issue in react-native here:

• [iOS] TextInput autoFocus called in didMoveToWindow causing transition glitches with UIKit facebook/react-native#56595

Changes

Merely adds the issue reproduction

Before & after - visual documentation

Caution

You may not see an issue with the video. I recommend downloading it, watching it a few times, stepping frame by frame though it. The transition is broken in two ways:

1. It doesn't progress continuously forward. At one point it jumps back, creating a flicker.
2. The keyboard has a dark tint and then switches to its final theme
