[Bug] Pasting multiline text triggers auto-submit and strips newlines (v0.89.0 - 0.92.0) #10065
Description
What version of Codex is running?
0.89.0, 0.90.x, 0.91.x, 0.92.0
What subscription do you have?
Pro
Which model were you using?
all
What platform is your computer?
Windows 11
What terminal emulator and version are you using (if applicable)?
VSCode Terminal / Windows Terminal / PowerShell
What issue are you seeing?
When pasting a large block of text with multiple newlines into the CLI, two issues occur simultaneously:
Auto-send: The CLI immediately interprets the paste as a submission command (as if Enter was pressed), without waiting for user confirmation.
Newline stripping: The content that gets sent to the model loses all line breaks, collapsing structured text (tables, lists, logs) into a single line/paragraph.
I have confirmed that rolling back to v0.87.0 resolves this issue completely (text pastes correctly, retains format, and waits for Enter).
What steps can reproduce the bug?
Start the Codex CLI (v0.89.0 or newer).
Copy the following long block of text (which contains intentional line breaks, tables, and lists).
Paste it into the input field.

bash
管理者として実行、または tmp_path を確認
pytest test\unit\contracts\contract_loader.test.py -v --basetemp=F:\temp
What is the expected behavior?
The text should be pasted into the input buffer exactly as copied (preserving the visual structure and newlines) and should wait for the user to press Enter manually before sending.
Additional information
This appears to be a regression introduced after v0.87.0. The handling of standard input or paste events seems to have changed, causing the CLI to interpret newlines in the clipboard as submission triggers.
