Large PRs block page load

Pull requests with a lot of changes are freezing the whole page/tab for a few seconds. A new diff tab just like the one in the branch page would be awesome.

Personally, when I have to deploy something in the next two minutes, it feels kinda annoying. Every single time when I refresh the page to check if the build finished or if the pull request got approved I have to wait a FEW MORE SECONDS just to be able to click something.
