Steps to reproduce

Open the ChatGPT Linux desktop app.

Copy aaa:bbb to clipboard.

Paste into the message composer (Ctrl+V or Shift+Insert).

Expected

Only aaa remains (the : and everything after it on that line is removed).

Workarounds

Pasting aaa: bbb works; editing afterwards to aaa:bbb also works.

Pasting inside a code block (…) works.
