Pasting multi-line text in Codex CIL only keeps first line and auto-submits on Windows

[stryio]

What version of Codex is running?

v0.20.0

Which model were you using?

No response

What platform is your computer?

Windows

What steps can reproduce the bug?

When pasting multi-line text into the Codex CIL chat input box, the input field does not handle line breaks properly.

Steps to Reproduce

Open the Codex CIL chat input box.

Copy a multi-line snippet (e.g., three lines of text).

Paste it into the input box.

Observed Behavior

Only the first line is shown in the input box.

The presence of a line break in the pasted content immediately triggers a “submit” action, sending the conversation automatically.

Impact
This prevents users from pasting multi-line commands, code blocks, or structured text,.

What is the expected behavior?

All pasted lines should remain in the input box.

The user should be able to edit and review before sending.

What do you see instead?

No response

Please prioritise this issue if you can, it keeps being a major problem for me.

Would be a big QOL.

This is the most pressing usabiltiy quirk I'm finding after the 0.22.0 update

Would scaling back to a previous version resolve this?

There is no previous version - this issue exists since the first official Windows build.

I figure out a temporry fix for this - paste into chatgpt.com or desktop app but not the cli- "keep all context & condense it into a dense LLM readable ( does not have to be human readable form) in 1 line without line break" followed by the text - doesn't matter how long it is, the output might ben 100s of words, but without the line break, it still gets pasted on codex cli. Hopethis helps until they bring us an update soon.

Please prioritize this as I have stopped using codex because of this annoying issue. Its more than QoL issue, codex is a no go till this is fixed.

I disagree. I compare them from time to time - Codex's model response quality is by far better, so I prefer it for the type of large codebases that I work with. And patiently waiting for the UI shortcomings to be all eventually resolved one by one. Now, the Windows build is very solid, I stopped running it in WSL.
