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

Sections (~37 bytes removed 📉 [gzipped])

name                          parsed_size           gzip_size
jetpack-cloud-partner-portal        +30 B  (+0.0%)      -37 B  (-0.0%)

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.
