Container, setAll active does work but setAll visible doesn't?

Phaser 3

I’ve got a container with some sprites and after each player move, the sprites in the container are changed.

It seems that for setting the active property of all sprites I can either use setAll() or Container.each(setActive.. but in order to set visible for all sprites I have to use Container.each ?

// this doesn't work
myContainer.setAll('visible', false); // all sprites are still visible
// this does work
myContainer.each(function(sprite) {sprite.setVisible(false) } ); // ok

// this works
myContainer.setAll('active', false); // also ok
// and this also works
myContainer.each(function(sprite) {sprite.setActive(false) } );

So I can get the code to work, but I don’t quite understand why after setAll('visible', false) all sprites are still visible. I mean, how can I know which properties do or do not work like this, or why doesn’t setAll always work the same?

setAll checks if the Object has the property.
A Sprite (GameObject) does have ‘active’ but not ‘visible’ as property after initialization (I guess).
So only use setAll when you know the Object has the property.

This is a quirk of SetAll(). It uses a hasOwnProperty() test, and visible is not an own property.

In this context, it seems like a bug.
