Description

The application of block gap styles globally for Columns blocks works in the site editor but not the frontend or post editor. It does appear to be working for other blocks such as the Cover block.

Step-by-step reproduction instructions

1. Navigate to Appearance > Editor
2. Add Columns and Cover blocks to a page and give them some content
3. Navigate to Global Styles > Blocks > Columns and give it some block gap
4. Confirm the Cover block displays the block gap in the editor
5. Save and view on the frontend. Notice the lack of block gap
6. Back in the site editor, adjust the global block gap style for the Cover block
7. Save the page and confirm it is rendered correctly in both the editor and frontend
