Thinking makes UI jitter

[logar16]

Describe the bug

Sometimes (not always) when the model is doing thinking, the UI starts to jitter a ton. Resizing the terminal doesn't help. Seems to happen more if I interrupted thinking (Esc or Ctrl + C) and then it resumes some other task. It is painful to look at. Please make it stop!

Affected version

GitHub Copilot CLI 0.0.411

Steps to reproduce the behavior

1. I think a way to do it sometimes is have a model do some thinking
2. Interrupt the thinking maybe do something like /context to add some other UI elements and turn on reasoning display
3. Have it start thinking again

I don't think it's reliable, but it keeps showing up at random times and it is driving me crazy! I believe it happens in both Windows Terminal and VS Code terminals though I've just been using VS Code the last few days so I'm not sure if it's unique to VS Code.

Expected behavior

I would expect the text to smoothly scroll up as new text is added, there should be no jitter or going up and down. There should be a key combo or command I can use to force it to reset view.
