TIWAdvImageButton enable disable at runtime doesnt change image

Embarcadero® Delphi 10 Seattle Version 23.0.20618.2753
IntraWeb 15.0.23
TMS IntraWeb Component Pack Pro v5.9.3.1

Setting the enabled property to false at runtime doesnt change the image to the disabled picture that I have loaded for the TIWAdvImageButton.

Can these properties be affected at runtime for the TIWAdvImageButton or does this component not have these capabilities?

I figured out that I have to trigger the Onclick property instead of the OnAsyncClick to affect the properties of this button.
