[Bug] Backspace Input Handling Breaks During File Path Autocomplete

Bug Description
First of all, thank you so much for all the effort you’re putting into this product. I really enjoy working with Claude Code, and it adds a lot of value for me.

There’s one issue I keep running into: when I press backspace, it doesn’t immediately delete text. Instead, the cursor moves, and I have to keep pressing backspace until it finally “catches up” and starts removing characters as expected. This happens more frequently when I’m trying to add a file using the @ symbol, and it becomes even more noticeable when the directory being searched is large.

I think this is a windows terminal specific thing, cause I haven't noticed this when using the claude agent in Rider for example. It's probably a React render issue, cause I have seen similar issues in our own product where React was re-rendering when it shouldn't.
