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

App Entrypoints (~3 bytes removed 📉 [gzipped])

name                 parsed_size           gzip_size
entry-gutenboarding        -27 B  (-0.0%)       -3 B  (-0.0%)

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

Sections (~3439 bytes added 📈 [gzipped])

name              parsed_size           gzip_size
gutenberg-editor     +12107 B  (+1.4%)    +3439 B  (+1.5%)

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.

I tried testing this locally but I can't spot the Page navigation dropdown in the header. Is there anything that I might be missing in terms of testing instructions?

Maybe some of the newer Gutenberg updates are changing the format of the top bar?

[johnHackworth]

oh, folks, sorry for the lack of instructions, I wasn't thinking anyone would try to test this yet!! I'll add some better description today or tomorrow

I don't think that would necessarily affect the display since it looks like this should be rendered on top of the iframe. At worst new updates would cause it to be slightly misplaced imo. 🤔
