Additional notes

Reported by Reuben from JUCE on Discord:

I'm trying to create a function block named Virtual MIDI 1.0 on a virtual UMP endpoint.

After creating the endpoint, I get an Added callback through the MidiEndpointDeviceWatcher. When querying the callback'sMidiEndpointDeviceInformation argument, using GetDeclaredFunctionBlocks(), the name of the block is reported as Virtual MIDI1.0. The second space character is omitted.

I'm on Windows 11 Canary Build 27802.rs_prerelease.250222-1646. The MIDI services version is customer preview 2, 1.0.3-preview-11.250228-237

Fixed for next preview.

The issue was I was trimming spaces from the end of the first chunk of name data when I shouldn't have been. In this case, the space just happened to be at the end of the first name message, and so was trimmed off.
