Site Editor: list view layout in Data Views is not displayed correctly

Impacted plugin

Jetpack

Quick summary

When going to any listing with the List View option, like Templates or Pages, the layout is off:

I'm able to reproduce this on Simple Sites, and with a JN site with the GB plugin active (v 19.5.0), and Jetpack connected.

Steps to reproduce

1. Start with a site with the latest GB plugin version 19.5.0, and JP connected. You can use a Dotcom Simple Site, too.
2. Go to Appearance → Editor → Templates (or Pages)
3. Change the display view option to List.
4. Check the listing.

@manzoorwanijk It seems that the import in #39230 (see e63e6cf) bled over to the styles in the site editor. Do you think we could do without it? Could you take a look at it?

Thank you!
