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

App Entrypoints (~4 bytes removed 📉 [gzipped])

name                   parsed_size           gzip_size
entry-subscriptions         -126 B  (-0.0%)      -17 B  (-0.0%)
entry-domains-landing       -126 B  (-0.0%)      -17 B  (-0.0%)
entry-browsehappy           -126 B  (-0.1%)      -17 B  (-0.0%)
entry-main                   +66 B  (+0.0%)       +7 B  (+0.0%)
entry-login                  +66 B  (+0.0%)      +21 B  (+0.0%)
entry-stepper                -42 B  (-0.0%)       -4 B  (-0.0%)

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

Sections (~575 bytes removed 📉 [gzipped])

name            parsed_size           gzip_size
purchases           +2023 B  (+0.1%)     +185 B  (+0.0%)
site-purchases      +1523 B  (+0.1%)     +304 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.

Async-loaded Components (~738 bytes removed 📉 [gzipped])

name                               parsed_size           gzip_size
async-load-automattic-help-center       -524 B  (-0.1%)     -738 B  (-0.4%)

React components that are loaded lazily, when a certain part of UI is displayed for the first time.

Legend

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.
