Instance on Points - Propagate Instance Attributes

Please let attributes on "instance" domain be propagated from the input instances to the output instances of an "Instance on Points" node.

Visualizing the issue:

When you use "instance on points", the attributes of the "points" are correctly propagated to the resulting instances.

However, the attributes of the input instances (when on instance domain) don't get propagated.

Image 1 : Input instances (from collection info) have an attribute "att" appearing in the spreadsheet. This attribute is in instance domain:

Image 2 : Output instances, though, don't get the attribute propagated.

Please let this attribute propagate.
