iOS auto-capitalization not working after pressing enter

[kasrak]

I'm re-filing #2632 since the issue is still present in Quill 2.

Steps for Reproduction

1. Visit quilljs.com/playground/snow on an iOS simulator/device
2. Focus the editor. Note how the shift key is activated for autocapitalization as expected.
3. Type "Hello.", then press space. Note how the shift key is re-activated for autocapitalization as expected.
4. Hit enter.

Expected behavior:

Shift key is re-activated for autocapitalization.

Actual behavior:

Shift key is not activated, so whatever you type won't be capitalized.

Platforms:

iOS 17 Safari

Version:

2.0.2
