I spoke with Venkat and we're aligned on the purpose of the change.
@v-dirichards , is there a preview url where we can confirm that the change is being reflected as expected?

[JaredMSFT]

I approve the intent and purpose of the change, can we get a preview url to ensure it's going to be rendered the way we anticipate?

@JaredMSFT - The change is in the metadata, so it won't render anywhere on the live site.
