Clicking search result while on non-root page goes to page not found

[jdkoren]

On v0.30.0+1. If you are on a non-root page and use the search bar, clicking a search result goes to a nonexistent page. Steps to reproduce:

1. grind serve-test-package-docs
2. Open a browser window and navigate to the served pages on localhost.
3. Enter some text in the search bar and click on a result.
   • On the root page, this should work just fine.
   • On any other page, it will most likely go to a page that doesn't exist. [BUG]

Similar problem as #2117, but it's the search result items rather than the script itself. The script constructs a list where each item uses an incomplete href, expecting base href to take care of the rest. Source
