Lighthouse doesn't support frameset or measure frames

#### Provide the steps to reproduce
1. Run LH on

```
lighthouse http://www.franciszkanie.rybnik.pl --max-wait-for-load 70000
# or
lighthouse http://www.bl-karolina.katowice.opoka.org.pl/index.html --max-wait-for-load 70000
# or
lighthouse http://www.nspjbrzeziny.pl --max-wait-for-load 70000
```
#### What is the current behavior?
Returns an error:

`Runtime error encountered: Something went wrong with recording the trace over your page load. Please run Lighthouse again. (NO_FCP)`

#### Environment Information
* Affected Channels: CLI, DevTools
* Lighthouse version: 6.2.0
* Chrome version: 84.0.4147.105
* Node.js version: v14.8.0
* Operating System: Ubuntu 20.04.1

Start by reproducing the failure with one of the listed Lighthouse CLI commands and compare the CLI and DevTools behavior. Done means Lighthouse can process pages using frameset or frames without the NO_FCP trace error; the issue names no files or tests, so locating the relevant handling will require project research.
