In the new UI when reviewing a run there is no way to copy the URL that is part of the waterfall. this can only be done manually by standing on the URL and then copying is letter for letter. These URLs are many times very long.
This actually used to work and for some reason was stopped where you could click on the link and it would open the URL in a new browser window but again this has stopped working for some reason.
