emulation: failed to load devices
Describe the bug
The eumlation-load doesn't work for kestrel devices, no devices are loaded if multiple devices are tagged. However, if only the ec device XXXXXXX is tagged then emulation-load works as expected.
Below is the list (obscured) of the tagged devices:
$ fwupdmgr emulation-untag

Choose device [0-6]:
Steps to Reproduce Preparation:
- start daemon
- connect kestrel usb devices
- fwupdmgr emulation-tag (select the listed devices)
- stop daemon
- disconnect the kestrel usb devices
Recording:
- start daemon
- connect kestrel usb devices
- fwupdmgr emulation-save all.zip
- stop daemon
- disconnect the kestrel usb devices
Play:
- start daemon
- fwupdmgr emulation-load all.zip
- fwupdmgr get-devices --filter=emulated ==> no devices are displayed
Attachments:
- emulation-data: all.zip
- daemon runtime log when recording: daemon-connected-host-save.txt
- daemon runtime log when playing: daemon-host-only-load-zip.txt
Expected behavior The tagged devices should be listed.

Additional questions
- Operating system and version: Ubuntu 24.04
- Have you tried rebooting? Yes
- Is this a regression? No
Can up please attach an emulation with all devices tagged? This will make working out the problem in the daemon a lot easier to track down.
Can up please attach an emulation with all devices tagged?
The other components are gtype devices enumerated within ec that cannot be tagged (i.e.: lack of can tag for emulation flag), the rest component in this plugin is the rmm device that is missing from kernel is due to known issues.
lack of can tag for emulation flag
Can we add the flag in _init() for those devices? or @superm1 maybe a heuristic makes sense, e.g. if you're adding a child to a device that can tag-for-emulation maybe it makes sense to automatically tag the child with the same?

If the children are normally made automatically by the plugin I don't think they really need to be can tag; particularly in the case of a proxy device.
How about when we tag a device that is proxy for other stuff for emulation we also tag everything it's a proxy for?
