Volume mute (C00) doesn't work after a tone portamento (305).

[nikku4211]

Whenever I do a 3xx tone portamento on a note and use C00 to mute it, it doesn't mute.

Strangely enough, the same tone portamento followed by E00 mutes just fine.

Here's the module showing the bug. First pattern demonstrates it, second pattern demonstrates the workaround.
