I'm getting a build error from yarn on this line -- I think it's supposed to be selectSiteId?

Suggested change

	import { selectedSiteId } from 'calypso/state/help/actions';
	import { selectSiteId } from 'calypso/state/help/actions';

How weird I didn't see any error... anyway, thanks!

Here is how your PR affects size of JS and CSS bundles shipped to the user's browser:

App Entrypoints (~75 bytes added 📈 [gzipped])

name                   parsed_size           gzip_size
entry-main                  +105 B  (+0.0%)      +33 B  (+0.0%)
entry-login                 +105 B  (+0.0%)      +33 B  (+0.0%)
entry-gutenboarding         +105 B  (+0.0%)      +31 B  (+0.0%)
entry-domains-landing       +105 B  (+0.0%)      +38 B  (+0.0%)

Common code that is always downloaded and parsed every time the app is loaded, no matter which route is used.

Sections (~151 bytes added 📈 [gzipped])

name    parsed_size           gzip_size
backup       +144 B  (+0.0%)     +151 B  (+0.1%)

Sections contain code specific for a given set of routes. Is downloaded and parsed only when a particular route is navigated to.

What is parsed and gzip size?

Parsed Size: Uncompressed size of the JS and CSS files. This much code needs to be parsed and stored in memory.
Gzip Size: Compressed size of the JS and CSS files. This much data needs to be downloaded over network.
