Thread in - no option to expand to see full function input

I LOVE the new ability to see thread (history) in the backend.

One request I would have to be able to see the FULL function call parameters PROVIDED. As far as I can see I cannot expand the view of the INPUT. I can use INSPECT in the browser and I can see that the full string is there, but unlike the OUTPUT there is not clickable element that allows the input to expand?
Or I am missing something?
