I use the following syntax to enter figured bass
\version "2.26"
\score {
\new Staff <<
\context Staff \figuremode { <[3-]>4 }
\new Voice { \clef bass c4 }
>>
}
but, as in this example, it falls over if markup or the [ ] notation is
used as the markup or brackets appear as separate "figures"
Is there any easy way round this?

(In case you are curious:
I think I adopted syntax because it allows the figures to follow the
context of the music, as in 18th c scores, rather than being aligned
across a whole system as in later practice)
