Twenty Fourteen: no space between Buttons block and Columns block on front end

[algorithmsunlocks]

Follow the Steps to reproduce the issue.

1. Activate the Twenty-Fourteen theme.
2. Choose a Button and a column block.
3. Add some text.
4. Apply to customize styles
5. Now check it on the user side.

It is looking proper in the editor but having issues on the user side.
I have attached a video for better understanding.

The Button block's small default bottom margin was ​removed in GB34546, which resulted in no margin on either the Buttons or Button blocks for Twenty Fourteen and other themes. I would have recommended a default margin above and below the Buttons block for any theme, but Twenty Eleven gives each individual link a top and bottom margin of 20px and Twenty Seventeen gives each a top margin of 2em.

With Gutenberg 16 (and probably the next WordPress version), the Buttons block has a setting to add a specific margin to the Buttons block. I think the current workaround of adding Spacer blocks could be easier than finding that setting in the sidebar for classic themes.

It seems to be a possible bug in the Twenty-Fourteen themes. Why should I use the spacer blocks instead of normal?
