"Open report" button doesn't show the report

[DEVTomatoCake]

Describe the bug
The "Open report" button shown when comparing results between builds only shows the blank lighthouse page prompting to upload a scan. Instead, it should load the data somehow and display it, otherwise, this tool is essentially useless.

To Reproduce
Steps to reproduce the behavior:

1. Open a Lighthouse report page (don't have a public URL anymore as hosting doesn't make sense with this bug)
2. Click on "Show report"
3. URL is https://googlechrome.github.io/lighthouse/viewer/ instead of the actual report

Expected behavior
I've expected to see the actual report instead of a blank page which prompts me to upload a scan, which I don't have because that's something the server should handle.

It also doesn't look like there's a redirect happening causing query params to get lost, the target url just doesn't contain any.

Environment:

• OS: Windows
• Browser: Chrome
• Version: 120.0.6099.111
• LHCI server & CLI running latest version
