Open asset in the scene object menu: the context menu of a scene object row has an Open asset entry below Select asset that does the same as a double click on the asset in the asset panel, so it selects the asset and opens its tab; kinds without an editor of their own (sprite, camera, text, collider) are only selected, just like the double click there; e2e 01 right clicks a behavior row and checks the open tab (#176)
