how to beam non-tuplets with tuplets?

[Adam James Wilson]

It seems you can beam together tuplets followed by non-tuplets (v. 2.11):

\times 2/3 {c'16[ c'8 } c'16 c'16]

But beaming together non-tuplets followed by tuplets fails with an
"unexpected ']'" error:

c'16[ c'16 \times 2/3 {c'16 c'8 } ]

Any known methods/hacks to get the second beaming example to work?
