@MarkConig thanks for the feedback! Your right and your feedback is helpful! So testing with thingmark I can reproduce the behavior as your described (also as @usami mentioned) Did not test it further with MT and AT but I think that I could rely that what you mentioned in your post is the current situation.
Also further check in PTC database I found the following article:

Especially the last one saying:
he Eye gaze cursor in Vuforia View for Hololens is not displayed after tracking a ThingMark or a Model Target
>>>
Description
==============
The Eye gaze cursor in Vuforia View for Hololens is not displayed after tracking a ThingMark or a Model Target
The Eye gaze cursor is shown in an Experience with Spatial Target
Resolution
=============
The Eye gaze cursor only appears when there is something that requires gaze+air tap to interact with. The cases where this is true are:
All experiences with a Spatial target, as the spatial manipulator buttons require gaze+air tap
Any experience that contains a widget when the Click event is bound or executes JS, except if the device is a Hololens2 and the only such Widget(s) are 3D buttons.
So following the logic on this article I simple defined e.g. the following dummy function on the same Project but with thingmark:
//----------------------------------------------------------------------
app.myClick=function(){
console.log("app.myClick();");
};
And added in the UI js box for the click event on the both model widgets (previous project attached on this topic)
Afterword's I tested it and it worked with thingmark as target - it shows again the gaze symbol
