pending hosts/service with a downtime throw error "Undefined index: PENDING-HANDLED"

[log1-c]

Describe the bug

Having a modeled BP where inside one node there is a object that is in a pending state and has a downtime (or supposedly any handled state) this causes the BP to throw an error when accessing that node.

To Reproduce

Have a BP with a node containing a host/service in pending state and add a downtime to it.

Tree view works:

Same process in tile view:
the pending node is in the Front End node

thrown error:

Undefined index: PENDING-HANDLED

Pending objects without a downtime work without problems.

Expected behavior

handled pending objects should behave the same way as pending objects.

Thanks for the report! Reproduced it , only with a pending service though. A pending host doesn't cause this on my end.
