1) go to https://prerender-test.appspot.com/
2) type www.bbc.co.uk in the input field and press "prerender" button
3) wait for a short while, e.g. 5 seconds, click the http://www.bbc.co.uk link 

Actual result:
It's navigated to the prerendered page www.bbc.co.uk, but the page wasn't loaded completely and the loading seemed stopped.

Expected result:
It's navigated to the redirect page www.bbc.com, and the page gets loaded completely eventually.

Additional note:
If in step 3, I open the www.bbc.co.uk link in a new tab, everything works as expected.

The issue was filed when we experimented prerendering 6 years ago, and the code was removed here https://bugzilla.mozilla.org/show_bug.cgi?id=1383876 This issue is no longer valid.
