Does renderPreviewHTML only work for certain symbols?

Hi,

I'm using symbolUtils renderPreviewHTML to generate preview images of symbols. I've noticed that this function only seems to work with certain symbols types. For instance, I cannot get it to work with any 3D symbols, or with web-style symbols. I usually get an error in the console, for instance:

previewSymbol3D.js:formatted:525 Uncaught (in promise) TypeError: b.getItemAt is not a function
at Object.B.previewSymbol3D

I cannot find any documentation regarding this in the API. Does anyone know?

An example of a symbol that does not work with renderPreviewHTML:

{

type: "polygon-3d",

symbolLayers: [

{

type: "extrude",

size: 10, // extrude by 10 meters

material: {

color: [92, 92, 92, 1]

edges: {

type: "solid",

size: "3px",

color: [92, 92, 92, 1]

}

]

}
