The menu item sends no artboard, so the engine fell back to the first one even with another
active in the Artboards panel.
The frontend fills in the active artboard (the view's, as the Artboards panel and navigator
show it) for select.allOnArtboard, as it already did for Paste in Place / in Front / in Back
(#693); the two now share one block, and the index is kept within the artboards. An explicit
artboard still wins; the engine is unchanged.
The test makes artboard 2 active, then 1, and invokes the menu item each time, then passes
artboard 1 explicitly with artboard 1 active.
