What happened? How did it happen? What are the steps to replicate the issue.
As expected, the text on the "Summarize" button is centered.
When clicked, the text changes and a spinner appears. On mobile, this causes the text to shift left until the spinner disappears. On the desktop, the button expands and the input box contracts.

What did you expect to happen? Describe the desired functionality.
While this is not technically a bug, I would expect the spinner to be positioned with absolute to not move the text and the button to be large enough to not change sizes as it iterates through its three states.
