Staff-initial tuplet bracket extent bug

Hi,

The extent of the outer tuplet bracket (4:5) below is incorrect; the outer
tuplet bracket should cover both inner tuplets, but it instead covers only
the second of the two inner tuplets:

%%% BEGIN %%%

\new Staff
{
  \tweak text #tuplet-number::calc-fraction-text
  \tuplet 4/5
  {
    \tuplet 3/2
    {
      \time 5/4
      c'4
      d'4
      e'4
    }
    \tuplet 3/2
    {
      c'4
      d'4
      e'4
    }
  }
}

%%% END %%%

The bug appears narrow; the output above is corrected if ...

1. the lexical position of `\time 5/4` is moved out of the innermost
tuplet, or
2. `\new Staff` is changed to `\new Voice`, or
3. any note, rest or chord is introduced before the tuplets, or
4. `\set tupletFullLength = ##t` is added to the example.

The correct output looks like this:
