Currently in Assistant, if you click the copy (to clipboard) button on a response from a thinking model like R1, it will also copy the 'thinking' section to your clipboard.
I'm not sure if that's the best thing to do. Personally I would think that if the 'thinking' section isn't expanded, then it shouldn't copy it to clipboard.
But if the 'thinking' section was expanded, then it should copy it to clipboard.
