Describe the bug

Since the update to Gemini CLI version .34, there is a severe bug. When pasting a large amount of text into the prompt window, it automatically executes (submits) before pressing Enter, and even before all the text is fully pasted. This issue has become much worse in the .34 release.

To Reproduce

1. Update Gemini CLI to version .34.
2. Copy a large block of text.
3. Paste it into the Gemini CLI prompt window.
4. The prompt executes automatically without waiting for the user to press Enter.

Expected behavior

The CLI should wait for the user to press Enter before executing, allowing the user to review or edit the pasted text.
