Sending transitions to groups where only some devices support them

[deviantintegral]

I have light groups that contain some devices that can do transitions (like light bulbs) and some that don't (like light switches and plugs).

When I send a command with a transition set to a single device, even if it doesn't support the transition, it will turn on or off. However, if I instead send the command to a group, the state of devices that don't support transitions don't change.

What's interesting is that when I send the command only to the device, I get this error in the logs:

Error 2022-12-18 16:57:25 No converter available for 'transition' (10)

Is this expected? I couldn't tell from the docs if sending unsupported attributes to devices in general should result in no command being sent at all, or in the unsupported attributes being ignored.
