Bug: `textarea` inputs in Safari stop accepting input if certain lines are deleted about react

[Nedomas]

I don't think this is related to deleting. I get the same problem if I start entering text on a previously empty line, but one that has content in lines after it.

For example, enter this into the textarea:

1
2

4

Then click on the missing line (where 3 would be) and try to start typing - it won't work. This happens both with controlled and uncontrolled textareas.

@iansan5653 Nice bug writeup! I am seeing this issue too https://jsfiddle.net/bilgehansolo/0vmL5cse/ here is the same code on a fiddle. Also tried passing the value as a defaultValue instead of children, it still had the same problem.

Also wanted to note that this is probably not a safari bug https://jsfiddle.net/bilgehansolo/3mwroLys/ textarea as pure html element works as expected.

Instead of setting the value inside the node, I refactored it to use a useEffect and set the actual DOM nodes .value. The bug seems to not be present in this case. https://jsfiddle.net/nkrLvm7w/

Oh interesting. Maybe a better title than would be "textarea inputs in Safari stop accepting input on certain empty lines" 🤔

I wonder if this is a React bug or a ReactDOM bug.
