SBUS decoder not working for true SBUS (inverted leveles, i.e. idle low)

[mha1]

True SBUS physical layer is defined as idle low 100kBaud, 8, e, 2. The DSView Futaba SBUS decoder can't decode true (idlw low) SBUS. Checking the Invert Signal option results in correct UART data but the SBUS decoder doesn't work.

Note: Idle high SBUS signals can only be correctly decoded after applying the changes made in https://github.com/DreamSourceLab/DSView/pull/792/commits to the Futaba SBUS decoder shipped with DSView1.3.2. But even with those changes idle low SBUS signals can't be decoded while idle high SBUS signals can be decoded as expected.
