Feature Grid block - When adjusting Column Gap and updating changes, editor view doesn't look the same

[andeng1106]

Describe the bug When adjusting Column Gap for Feature Grid block and updating changes then refreshing editor, the editor view doesn't look the same anymore. But when copying the same block, it looks the same again.

Note: This issue also happens on Wordpress 5.9 but it might be nice to fix this.

To Reproduce Steps to reproduce the behavior:

1. Add Feature Grid > Variation: Zigzag
2. Change Column Gap to 99 (Feature Grid > Style > General > Column Gap
3. Update changes
4. View in "Preview in new tab" or "View Page" (expected view)
5. Refresh editor and check if editor view changes (where bug found)
6. Duplicate Feature Grid created
7. See if the view from the first Feature Grid block changes back to as expected.

Expected behavior

• After refreshing editor, the Feature Grid view from before should look the same without needing to duplicate it again and again.
