ActiveDocument.resizeImage doesn't resize layer effects

I noticed something when I made a script for batch-exporting a large number of icons:

When I scale things manually (Image > Image Size), the layer effects of my artLayers scale accordingly to the document size.

When I scale things in code, the layer effects are NOT scaled accordingly to the document size. So if I scale something down then the layer effect will appear to be twice as thick/strong as before - why?

You can try it yourself:

Create a doc, with a new layer, paint something like a square and apply a stroke layer effect to it of something like 8px.

Run the below code:

var doc = activeDocument
doc.resizeImage(UnitValue(50, "percent"), UnitValue(50, "percent"), 72, ResampleMethod.BILINEAR);

The layer will still have a 8px thick stroke effect. But if you scale it manually the effect will scale along with the document.
How can I repeat that behavior in code?

Correct answer SuperMerlin

You could use AM code...

function resizeWithScale(Percent) {
var desc42 = new ActionDescriptor();
desc42.putUnitDouble( charIDToTypeID('Wdth'), charIDToTypeID('#Prc'), Percent );
desc42.putBoolean( stringIDToTypeID('scaleStyles'), true );
desc42.putBoolean( charIDToTypeID('CnsP'), true );
desc42.putEnumerated( charIDToTypeID('Intr'), charIDToTypeID('Intp'), stringIDToTypeID('bicubicAutomatic') );
executeAction( charIDToTypeID('ImgS'), desc42, DialogModes.NO );
};
resizeWithScale(50);

Well I guess that's how I have to work to get around this inconsistency. Thanks!

What inconsistency? Scaling styles has always been an option and feature as far as I can remember?  In Image  resize a setting option and an option in menu layer>layer styles>scale effects....

That is on by default
You cannot change that setting in code (DOM)
Therefore scaling manually VS scaling in code = Different results = Inconsistent
