Invisible rests

[stolz]

Is it possible not to hide bars with invisible rests using EasyABC 1.3.5.7?

The code below :

X: 1
L: 1/8
K:C
%%staves [1 2]
V:1 clef=treble
|z4 x4|
V:2 clef=bass
|C4 z4|

will result in:

In case, all the rests are invisible

X: 1
L: 1/8
K:C
%%staves [1 2]
V:1 clef=treble
|x4 x4|
V:2 clef=bass
|C4 z4|

the result is seemed to be unexpected:

The problem with invisible bars appears using only one voice too. The code:

X: 1
L: 1/8
K:C
|x4 x4|

will be rendered as an empty page in EasyABC
