Display bounding boxes on unloaded payloads

[sharktacos]

Is your feature request related to a problem? Please describe.

I'm trying to get bounding boxes to display for unloaded payloads using the extents hints attribute, following the example from the USD Cookbook.

This works as advertised in USDview. It does not work in Maya, and unloading a payload shows nothing in the viewport.

Describe the solution you'd like

Get bounding boxes to display for unloaded payloads using the extents hints attribute.

Describe alternatives you've considered

I would imagine that this might be something that would work in Hydra, but not in VP2. Of course, it would be nice if it worked in both. Currently, it appears to work in neither.

Additional context

Regarding Hydra, this issue may be related from OpenUSD:
"Storm not drawing unloaded payload boxes #2720"

Thanks for making the issue, in my opinion this feature would fall high on my list of things I'd like to see.

Cheers,
