Dimensions do not reliably update after orientation change on iPadOS in v0.76.0

[mhoran]

Description

After upgrading to 0.76.0 I found that Dimensions do not update reliably after orientation change on iPad. This seems to be the root cause of #47251.

This was not an issue in 0.75.0 but I have not been able to trace down the breaking commit.

Steps to reproduce

1. Install the application on an iPad simulator with yarn ios
2. Note the correct dimensions displayed
3. Change the screen orientation
4. Note dimensions do not change
5. On subsequent orientation change, sometimes dimensions do update, but not reliably
6. Note that dimensions will update if app is sent to the background

I've traced the issue to f22a5ef. Reverting this commit resolves the Dimensions issue and also fixes the KeyboardAvoidingView issue.

[mhoran]

Confirmed this is fixed by e271b23 which is included in 0.76.1.

I observed this bug with react native 0.74.6 (just for information)

Seeing a potential regression for this issue in 0.76.6 - came across this ticket hunting for solutions to a KeyboardAvoidingView issue which I am currently experiencing on an iPad as described in 47251)
