Obscure - SysEx messages with space (20h) in position 14 are fragmented

Obscure, but sharing to ensure folks don't loose as much time as I did trying to get a layout working right.

SysEx messages with a space (20h) in a particular position are fragmented in MD - in this case, position 14.  

The log shows a fragment of the message

In one sample case, what is received:

← 13:04.520 Length=6: 00 00 53 6F 20 6F 

What should have been received, highlighting the fragment in the true string

← 14:23.889 Length=29: F0 41 10 00 00 75 12 10 00 00 00 53 6F 20 6F 20 4A 61 7A 7A 20 47 72 61 6E 64 20 68 F7

Controls are not responding, so it is not just a log issue.

Workaround - In this case, I can change the fourteenth position - which is the third letter of program name - to _ or .  (What I did to get the correct output above, then edited to put the space back.)

I have not done troubleshooting to see if this is unique to the Roland header above, or if there are other issues at work.  It does not appear to be related to having a target with SysEx strings - started with a new layout, only a single control to request the SysEx, same behavior.
