Why is a Major 7th chord not played as such, when you use the shortcut ∆ ?

Sample score please. "at" -> "A∆" does play back, as does "a7" > "A7" and "at7" > "A∆7" but "a7t" > "A7∆" though indeed does not (other then the A itself), do you mean that?

It is A Major 7, so "at7" > "A∆7" makes sense, while "a7t" > "A7∆" does not, A 7 Major?

Technically, the triangle by itself - without the 7 - doesn't necessarily mean to play the seventh; many musicians use it to indicate a triad. The 7 should therefore always be included.

Still, it's not uncommon for people to omit it - similar issues for half-diminished (see #297246: Chord symbols: in some cases, 0 (zero) does not turn into ø), so at some point we should probably support this alternate notation style.

FWIW, there was a forum post or two about this, but apparently no issue submitted that I can find.

Also, to be clear, this issue isn't unique to playback, it is built-in to the parser that hasn't changed appreciably in many years. It's just that previously, the only way to recognize that the triangle wasn't implying the 7th already was to export to MusicXML. Now playback is there to tell the same story.
