Transfer Size is incorrect in resource-summary audit

See original GitHub issue

Provide the steps to reproduce

Run LH on https://test.lucacasonato.vercel.app/
View Keep request counts low and transfer sizes small diagnostics

What is the current behavior?

The Transfer Size is not correct. It is double, triple, quadruple, or 10 fold the actual value: It says 0.5 kb for Script in Lighthouse vs 48 bytes in network panel:

Here is a JSON export from Lighthouse on this page: test.lucacasonato.vercel.app-20200911T201026.txt

What is the expected behavior?

I expect Lighthouse to show the correct values.

Bisect gave me: https://chromium.googlesource.com/chromium/src/+log/41ce21f10c765a426cc990c4714506ee4424347c..1079b28e253fa321c8d9379fed1e69b5b5c6fbbb

For Paul’s example, I noticed in CLI I get two dataReceived events for that request. The first is 63390 bytes. the second is zero. The incorrect value that Lighthouse gets in devtools is 126780, which is 63390 * 2.

I believe I summarized the behavior of dataReceived in a previous PR, I’ll have to comb through this file’s history to find it. But I can definitely confirm this is a bug in Lighthouse’ DevTools integration.
