Extended cresc. dim. after adding bars [5.1.70]

Hi!
Updated to 5.1.70 and while tasting the morning coffee I just continue composing. So here are new discovery (here tested on empty project):

  1. Selected barline (the same on any selected note) and hit Shift+B to add bars. Entered “1” and hit Enter.

    Dorico added one empty bar on the position I selected…

    …but the diminuendo extended to 4 bars while 3 could be logical.

BTW if there is only one staff I test this, then everything is okay - added bar extends dynamics only by one bar as it should be.

  1. Even more! If there are 3 staves, then dynamics extends more by one bar. So it seems that the bug is “how many staves have linked dynamics, they will lenghten by that number”.

P.S. I didn’t read everything in Dorico manual, but I guess it should not work this way.
