Gutenberg Columns block border displays in editor but not on front end with Spac

I’m using the Spacious theme with the WordPress Block Editor and have run into an issue with the Columns block border setting.

I have an outer Columns block containing three columns. In the Block Editor, under Styles → Border & Shadow, I have set a 2px border.

The border displays correctly inside the Block Editor, but when I view the published page on the front end using Spacious, the border does not appear.

To determine whether this was a Gutenberg issue or theme-specific issue, I tested the same page/block setup with several other themes.

The border displays correctly on the front end with:

• Twenty Twenty-Five
• Hestia
• Kadence
• Ashe
• Sydney

The border does not display with:

• Spacious
• OceanWP

So the border setting appears to be saved correctly by the Block Editor, but something about the front-end styling in Spacious seems to prevent it from being displayed.

I’m specifically trying to use the native Gutenberg Border & Shadow control, rather than adding a custom CSS border, because I am teaching beginners how to use the Block Editor and want the front-end result to match what they create using the editor controls.

Is this a known issue with Spacious, or is there a theme setting or block-support setting that needs to be enabled for Gutenberg’s native Columns border to display on the front end?

I’d be happy to provide screenshots or any additional information needed.

Thank you!
