Affected Version: the version in production at chromium-review.googlesource.com

What steps will reproduce the problem?
1. Go to https://crrev.com/c/979334
2. Note that the URL expands to https://chromium-review.googlesource.com/c/chromium/src/+/979334
3. Try to find an easy way to get back to the short version of the URL

What is the expected output?

I would like to see a button (with the same icon as the one next to the parent commit URL) next to the review number that copies the shortened URL. I currently use a Chrome extension that crashes occasionally, and that only works on my corp profile.

What do you see instead?

No easy way to copy the shortened URL for a review.

Please provide any additional information below.

I imagine this would require some per-project configuration, because there's no way for PolyGerrit to know about custom domains. I think that would be worth the effort, because I do this (copying URLs around) multiple times per day, and I read documents and e-mails with Chromium review URLs in them multiple times per day. Having easily accessible shortened URLs would be a significant quality of life improvement.

Thank you!
