Thanks for the PR @shail-mehta 👍

Could you please add some further details to the PR description and test instructions?

I'm not sure exactly what needs to be tested here or the reasoning behind the layout configuration chosen. Also, tweaking the PR title to match what is happening in the code changes is always good (i.e. adding align and layout support).

I believe __experimentalLayout was stabilized to layout back in June 2023 via #51434.

Thanks for the Feedback. I will work on this.

@aaronrobertshaw I have Used layout instead of __experimentalLayout and also added testing instructions in description.
