What do you expect to happen?

It's technically a comment and the play button, just like F8, isn't smart enough to check if you can run that code block.

Hey Tyler,

I did not know that #Requires does not run on F8 (it treats it like a comment) - thanks for the info!

The idea is that the '#Requires' should be hidden from the Notebook. As of now it gets included in the markdown cell either we want it or not. I do not see the reason to show it in the Notebook, still I see the need to keep it in some ps1 files, in order to prevent from running when some predefine requisites are not met.

While we would rather not special case not seeing the Require block as markdown, the issue that this creates space between # and Require warrants fixing, and likely the easiest way to do that is through a special casing

We've removed the experimental notebook support in #3176, going to mark this resolved.
