This looks great! Very happy to see depreciated components replaced!

Couple little comments in there but overall this is looking really good!

[brian-smith-tcril]

do we need the <div> and the <p> here? my assumption would be that the <div> was needed before because the body wasn't a component, but now that we have <ModalDialog.Body> it might be redundant.

same as previous comment about probably not needing this <div>

@Mashal-m the linter errors on this should go away if you rebase (#78 fixed them)

Thanks for the PR, @Marshal-M! For expediency (we want to get another PR in today), we rebased and merged your code via #79. In other words, you can count this as a successfull contribution. :)
