Treemap double-counts JS resource reached via redirect

FAQ

• [X] Yes, my issue is not about variability or throttling.
• [X] Yes, my issue is not about a specific accessibility audit (file with axe-core instead).

URL

https://retirementcalculator.hsbc.co.uk/

What happened?

Network tab shows what happens handling the GET request for https://minerva.wealthwizards.io/pension-guidance/main.js The response is a 307 redirect, and the browser goes on to GET https://minerva.wealthwizards.io/pension-guidance/1.3.35/assets/main.js

However, Lighthouse's treemap report includes a box for both URLs, assigning the full size of that resource to both.

What did you expect?

I would expect to see one box for https://minerva.wealthwizards.io/pension-guidance/1.3.35/assets/main.js (redirected from https://minerva.wealthwizards.io/pension-guidance/main.js)

Lighthouse 11.0.0 the problem is back? I have a similar case and I don't know what is the reason. How to find the reason for duplicate scripts for this test. ?
