Auto-Capitalisation not working in certain scenario

[Zokii0]

Describe the bug
What I noticed is that Auto-Capitalisation doesn't work when we delete word(s)/letter(s) by swipping, neither with regular delete right next to punctuation mark, which bugged me out, as it works in Heliboard

To Reproduce

1. Type something
2. Use punctuation mark
3. Make space (only then works Auto-Capitalisation properly)
4. Type after that
5. Try to delete (by swiping on backspace/delete button, or by tapping it if coursor is next to 1st symbol right after space after punctuation mark)

Expected behavior
Auto-Capitalisation should work no matter if coursor is next to space after punctuation mark
