Windows Terminal Input And Render Bug

What version of Codex is running?

codex-cli 0.46.0

Which model were you using?

_No response_

What platform is your computer?

Microsoft Windows NT 10.0.26100.0 x64

What steps can reproduce the bug?

When I paste multi-line text into the Codex terminal on Windows Terminal, the first newline is interpreted as a submit action instead of inserting a line break. As a result, only the first line is sent and the rest is not entered as intended.
When using a Chinese IME, after committing a character, pressing Space causes the previously entered character to render as a blank (disappear visually) in the input field. This looks like a preview/rendering glitch.
