As of today we support CLI argument wise `--save-storage` and
`--save-har` in pdf/screenshot CLI command. But they are not working,
since we just close the browser rather than the context where we take
care of saving the artifacts.
`launchContext` has 4 usages:
- open/codegen there closing the browser / `SIGINT` will close it
gracefully
- pdf/screenshot there we will now close the page which will then
[here](b00579edb7/packages/playwright-core/src/cli/cli.ts?q=cli.ts#L503)
close the browser.
I did not find any tests except the [installation
test](3e84ab4701/tests/installation/playwright-cli-screenshot-should-work.spec.ts),
I'm happy to add one for both command if requested.
