What's Wrong?

When using the CLI, depending on whether I'm viewing the top/bottom of the conversation, or if I've scrolled up slightly, right-clicking highlighted text during active agent interaction triggers a bug. This happens especially when I'm asked for edit permission like:

Do you want to overwrite example_script.py? 1. Yes 2. Yes, allow all edits during this session (shift+tab) 3. No

I will now describe the two bug behaviors:

1. When the view is at the top or bottom of the conversation:

The view flickers, and the highlighted text is unhighlighted as soon as the context menu appears, which prevents me from clicking "Copy".

1. When the view is scrolled up slightly to review change suggestion (not at the top/bottom):

The same behavior as the first case occurs, but in addition, the view unexpectedly scrolls to the beginning of the conversation.

This issue is not caused by any changes in the highlighted text itself.

What Should Happen?

After right-clicking the highlighted text, the text should remain highlighted, and the view should stay in its current position without scrolling. The context menu should appear and remain open until I either click an option or click outside the menu to close it.
