Skip-filled tuplets crash 2.25.0

Hi,

Skip-filled tuplets halt execution in 2.25.0.

%%% BEGIN %%%

\version "2.25.0"

\new Staff { \times 2/3 { s2 s2 s2 } }

%%% END %%%

It's probably true that most users aren't using skip-filled tuplets. But
I've been using them for quite a while in previous versions of LilyPond
(for certain cases of complicated polyphony where compositional processes
transform some, or perhaps all, notes in one voice into skips).

Will skip-filled tuplets be allowed again in future versions of LilyPond?

Thanks for all the goodies in 2.25!

Trevor.
