I am encountering an issue with a unique form that sends each line of input as a separate request upon submission. I am looking to add a spinner at the end of each line, but I am facing a problem where instead of a circular spinner, I am getting a spinning "D" shape. I have attempted to adjust padding/margin for the spinner, but have not been successful in resolving the issue. Can anyone offer assistance? CSS is not my strong suit.
Edit: I have tested this on both the latest versions of Chrome and Brave.
