RDL UDP in top-level component is silently dropped in XML output

[amykyta3]

Given the following RDL input:

property my_rdl_udp {
    type=boolean;
    component=addrmap | regfile;
};

addrmap my_top_addrmap {
    my_rdl_udp;
    reg {} a;
} top;

The entry for the user-defined property is missing from XML export. This seems to only occur if the property assignment occurs in the top-level component.
The following XML I would expect is missing:

<user_properties>
  <my_rdl_udp>true</my_rdl_udp>
</user_properties>
