Once tablature mode is entered in a note, it can't be exited

[miesvanderrobot]

Loving the tablature support, especially since it supports capos and alternate tunings, which means I can actually support my tenor guitar!

Ran into an issue, though. Once tablature occurs within a note, it ends up applying the same tablature properties to all subsequent non-tablature music-abc blocks in the same note. Here's an example:

X:1
T:The Legacy Jig (just fine)
M:6/8
L:1/8
R:jig
K:G
GFG BAB | gfg gab | GFG BAB | d2A AFD |
GFG BAB | gfg gab | age edB |1 dBA AFD :|2 dBA ABd |:
efe edB | dBA ABd | efe edB | gdB ABd |
efe edB | d2d def | gfe edB |1 dBA ABd :|2 dBA AFD |]

{
  "tablature": [{
    "instrument": "mandolin", 
    "label": "Tenor Guitar (%T)", 
    "tuning": ["C,", "G,", "D", "A"],
    "highestNote": "e'",
    "capo": "2"
  }]
}
