Problem/Motivation
Dropbuttons on forms in conjunction with regular buttons can be misaligned due to discrepancy on the margins top and bottom.
Steps to reproduce
An example is a Feed Channel entity as provided by the Feeds module on a Drupal 9 install with Gin theme active.
The Feed Channel entity features a dropbutton + a regular button.
This can reproduced both using Claro and Gin, who depends on Claro:
Proposed resolution
The .dropbutton-wrapper CSS that sets margin top and bottom to 0.5rem is provided by Claro/core/themes/claro/css/components/dropbutton.css?rq2mag
The 1rem margin for .form-actions .action-link is also provided by Claro on core/themes/claro/css/components/form.css
They should be normalized.
