Usually be
const z2 = itemModel.get('z2');
// or const z2 = itemModel.get('z2', true); (no need to create a temporary model object, tho there is probably no performance issue here, handy optimization would be better.)

Symbolis used not only by markPoint, but also by line series, scatter series, etc.
In the current PR, only markPoint allows users to set z2, which results inz2: 100being missing in other cases. Is it intentional? If not, backward compatibility should be maintained. -
If users do not specify
z2, here a undefined-z2 will be set to an zr element, which is error-prone (z2 is not meant to be a non-number yet in zrender) and might degrade the performance (theoretically).
Summary: I think every place a z2 is about to set to a zr element, use a default number value to make sure it's a number.
e.g.,
symbolPath.attr({
zr: retrieve2(z2, 100),
...
})graphic.updateProps(polygon, {
retrieve2(z2, 0),
// ...
})The other place that sets z2 to zr elements in this PR follows this suggestion.
