[PORTAMENTO / GLISS] Portamento is played during note preview (SoundFont only)

[bkunda]

Issue type

General playback bug

Bug description

When a portamento/gliss line is applied to a note and set to the "Portamento" style, the portamento will be heard simply by selecting the note.

This only occurs when using a SoundFont. Expected behaviour: only the pitch of the note should be heard during note preview – not the portamento.
