That an internal OS system (help) opens in the OS browser I'm willing to accept. That
every browser says "please please make us the default browser" is annoying but hardly unique for Edge.
This is just the combination of the two.
I don't think enough people use Win+Type+Enter queries, nor F1 help in Windows to make the discussion very interesting compared to the really interesting ones like which browsers will open a hyperlink in a non-browser app.
