Tied enharmonics incorrectly notated

In Musescore 2.0.0. There are times in real repertoire when notes are tied to their own enharmonic duals, e.g., a C# to a Db. Although there is no straighforward way to say this, the "J" command on the second note does a pretty good job, unless the J'ing makes it need an accidental; the accidental does not display. Attempts to force the accidental on it destroy the tie. Restoring the tie obliterates the accidental.

Trivial to duplicate: make two equal notes (e.g., C), tie them, put an sharp on the first, J the second and the notation is already incorrect.
