Copy a pretty URL version of a Chromium issue (e.g. https://crbug.com/414843).

/*
Convert to a bookmarklet using: https://chriszarate.github.io/bookmarkleter/
When you're on a Chromium issue page, this bookmarklet copies the short URL to clipboard. Also offers a markup version, a snippets version, and the pure ID.
Example: https://crbug.com/445359 instead of https://bugs.chromium.org/p/chromium/issues/detail?id=445359&can=1&q=owner%3Ame%20OR%20reporter%3Ame%20OR%20cc%3Ame%20OR%20commentby%3Ame&sort=-modified&colspec=ID%20Pri%20M%20Status%20Owner%20Summary%20OS%20Modified
