Clarification about pending data on device disconnection

[toyoshim]

Should we keep all pending data that were sent with timestamps even after the device is disconnected, and send it if the device is available again when the specified time arrives?
It would be better to explain it explicitly in section 8. MIDIConnectionEvent Interface.

What do you think we should do?

I feel keeping pending data as possible by default would be consistent with other auto reconnection behaviors. If developers do not want to hold it, they can simply call clear() on disconnection event.

But data without timestamp, and data having overdue timestamp will be dropped on time.

The Core MIDI behavior is to send pending data if the device is connected at the scheduled time. If the device is not connected, the data is lost. Disconnection doesn't clear pending data.

This behavior seems fine for Web MIDI.

Step 9 of the open algorithm in the current spec suggests that data will queue in some way, which we may not want. Some decision and clarification would be good.
