Filebird gallery widget doesn’t display correctly?

New install of WordPress 6.2.2 with Twenty Twenty Three as my theme. Fresh install of the Filebird plugin as well.

An event just recently happened, so I loaded them images into a folder, and inserted a Filebird Gallery widget onto the page. The configuration shows in the right sidebar of the post editor, but the results look TERRIBLE in the editor and on the site. I selected “2 columns” but see only a single column. I see list bullets on the resulting page.

It looks like the contents of block-library/style.css are needed, but aren’t being loaded. If I inject the rules for blocks-gallery-grid from that file into the page, it displays fine.

Why isn’t the file getting included?

If I add a normal gallery widget to the page AFTER the Filebird widget, then the file wp-includes/css/dist/block-library/common.min.css?ver=6.2.2 is included and it works fine. But that feels like a bug.
