Closing iPad keyboard via button doesn't resize screen properly

Summary:
When using an iPad, on the world creation screen the screen doesn't resize properly if the keyboard is closed using the button in the bottom right of the keyboard.

The screen resizes properly if you tap away from the keyboard instead of using the button on the keyboard to close it.

Steps to Reproduce:
On an iPad (and maybe larger iPhones if they have the button to close the keyboard)
Create a new world and enter something in the "World Name" or "Seed" field.
Close the keyboard using the "close keyboard" button in the bottom right corner of the keyboard.

Observed Results:
The world creation screen does not expand to fill where the keyboard was until part of the screen is touched (eg scrolling)

Expected Results:
The world creation screen returns to the size and position it was before you opened the keyboard, regardless of how the keyboard was closed.

Notes:
I don't think this is a major issue, its just a minor annoyance. See https://youtu.be/39sY0w6FpQA for a video demonstrating the problem. This occurs on my iPad Pro (12.9-inch) (5th generation) but not my iPhone 13, mainly because the iPhone keyboard lacks that button. Larger iPhones might also have this issue. I don't recall this occurring in 1.8.20.30 preview, but it's possible I missed it.
