Missing number in broken triplet

[Hans Aberg]

I report this problem just for completeness. If one breaks up a  
triple into to two parts, as in the following example, the triplet  
number on the single note does not show. The code is
{
  \time 2/8
  \times 2/3 { e16 f16 } g8 \times 2/3 { a16 } |
}
It looks as in the attached GIF. (There is a beaming problem too, but  
this has been reported in other bug reports.)

If one makes sure each broken triplet has more than one note, then  
the triplet numbers do show. E.g.,
{
  \time 4/8
  \times 2/3 { e16 f16 } g8 \times 2/3 { a16 b16 } c8 \times 2/3  
{ d16 e16 } |
}
