Inspector: segment "Leading Space" input field topped at 10sp

The “Leading space:” input field in the Inspector is limited to a max value of 10 sp.

I have several occasions when this is too low a value:

(this is an example when 20 sp are needed; there are others with even greater values, but import from MS 2.3.2 creates other problems, so I cannot post them right now).

Notes:

1. Manually modifying the value in the .mscx does work: the score is loaded and formatted correctly.
2. So there is a workaround but, of course, the value cannot be modified in the programme UI, as this would truncate the leading space back to 10 sp.
3. The largest value I found is currently 25 sp; so I think that an increased max around 50 sp would be acceptable.
