Fix extrude button (#3718)

* Fix: regression on command bar buttons (remove drag)

* Revert "Fix: regression on command bar buttons (remove drag)"

This reverts commit 2404bcdf31.

* Make all elements opt-out of drag behavior by default, add comments around drag attribute

* Add vendor-specific user-select

* It won't do to make all elements opt-out, it ends up swallowing the drag events themselves!

* Sneaking in this email truncation nit that's bothered me

* Gotta remove that one more attempt at a generic "we made this clickable" element

* Make orbit continue to work when dragging over the AppHeader
