How can I record layer alignment baseline?

I was curious, so I recorded two actions, one aligning to canvas and one aligning to selection. I converted each to a script using xtools.

The only notable difference in the code is:

desc1.putBoolean(sTID("alignToCanvas"), true);

vs.

desc1.putBoolean(sTID("alignToCanvas"), false);

However, when the action is played, both versions will error and fail if there is no selection before running the action. Align to canvas shouldn't require a selection, as the scripts posted above demonstrate. Therefore I can only conclude that this is a long-standing bug in the action playback, as the boolean for canvas appears to be recorded into the action, even if not visible in the action panel interface.

Here is align to canvas via scripting listener:

// Align Active Layer to Canvas.jsx

/* 
ADSLefts      =   Align Left
ADSRights     =   Align Right
ADSCentersH   =   Align Centre Horizontal
ADSTops       =   Align Top
ADSBottoms    =   Align Bottom
ADSCentersV   =   Align Centre Vertical
null          =   insert "null" to quickly disable one of the two alignment options
*/

alignToCanvas(true, "ADSLefts");
alignToCanvas(true, "ADSTops");

function alignToCanvas(alignToCanvas, alignValue) {
	
	app.activeDocument.selection.selectAll();
	
	var s2t = function (s) {
		return app.stringIDToTypeID(s);
	};
	var descriptor = new ActionDescriptor();
	var reference = new ActionReference();
	reference.putEnumerated( s2t( "layer" ), s2t( "ordinal" ), s2t( "targetEnum" ));
	descriptor.putReference( s2t( "null" ), reference );
	descriptor.putEnumerated( s2t( "using" ), s2t( "alignDistributeSelector" ), s2t( alignValue ));
	descriptor.putBoolean( s2t( "alignToCanvas" ), alignToCanvas );
	executeAction( s2t( "align" ), descriptor, DialogModes.NO );
	
	app.activeDocument.selection.deselect();
}

Just to add to @Michael Bullo suggestion, record Select > All as action step, selection must be active when playing action, action will align to selection not to canvas.
