Beams follow note@ho #4232
Description
With the wonderful support for @ho/@vo and @startho/@startvo, @endho/@endvo (#4221 and #4211), a <note> may be visually shifted to the left/right. While a <slur> attached to that note can be shifted using @startho, a beam connected to that note remains unshifted (and cannot be shifted wit @startho, as it is not supported by the schema).
It would be desirable that beams enclosing shifted notes will be shifted visually as well (and stay connected to note stems).
Minimal example with three beamed notes; first and last note are shifted to the left or the right, respectively:
