 Was testing the latest version of Twenty Twenty-Two with 5.9 Beta 2. The
 pattern previews in the Pattern Explorer appear "off", many are too tall
 and are not rendering properly. Enabling the latest version of Gutenberg
 seems to resolve the issue. This leads me to believe "something" was not
 properly ported into 5.9 from Gutenberg.

 Example in 5.9 Beta 2 (incorrect):

 Example in 5.9 Beta 2 with Gutenberg active (correct):

 Tested in latest version of Chrome, WordPress 5.9 Beta 2, and Gutenberg
 12.1.0.
