+          VerticalContentAlignment is not decoration and not a duplicate of the line above it. A button's
+          content alignment defaults to Stretch and the Fluent template binds it straight through, so the
+          text block filling a 48-pixel button draws its line at the top of it. Every button class in
+          Phone.axaml sets this; the three on this screen are the only ones on the phone that carry their
+          own metrics instead, which is how this one came to sit high in its box.
