Revision searches with a prefixed at sign breaks search result links

Created by: soyarsauce

Hiya I've been loving this feature: https://about.sourcegraph.com/blog/search-multiple-revisions/ The result links work fine when using the vscode extension, but not in sg web; I presume because of the tag being prefixed with @ tripping up the url parsing, more details below:

• Sourcegraph version: 3.34.2, also Sourcegraph.com
• Platform information: Chrome 98.0.4758.109 + Firefox 97.0.1

Steps to reproduce:

1. Do a multi revision search OR single revision search with @ in revision (tag in this instance) name

• repo:^github.com/emotion-js/emotion@main:@emotion/[email protected] file:^package.json
• repo:^github.com/emotion-js/emotion$ rev:@emotion/[email protected] file:^package.json$

2. Click package.json result

Expected behavior:

See page/file view for package.json file

Actual behavior:

Hit a 404 page
