Thanks for putting the PR together @shail-mehta 👍

I've removed myself from the reviewers as I don't have the bandwidth for reviews in the near future.

To help those who can review, would you mind expanding on the test instructions? It helps to assume people coming to your PR have no context.

For example:

Also Check With layout width in Layout Settings
Check Settings in Editor and Frontend Side

Check what? What should be changed/set, and what's the expected outcome?

Thanks for the feedback. I will work on this.
