Parenthesised articulation issue

[Andrew Bernard]

Greetings All,

When setting a long tuplet of short note values, the parenthesizing of > is incorrect. It is otherwise correct. The run of 32s seems to be upsetting something in the engine room. Refer to the MWE below.

The error reported is as follows:

programming error: Improbable offset for stencil: inf staff space

Setting to zero.

continuing, cross fingers

Crossing my fingers did not help. :-)

Apologies for the somewhat lengthy MWE, but I only get this problem in this context, and have not found a shorter way to generate the issue.

What am I doing wrong?

Andrew
