requestMIDIAccess call with sysex support will be stuck

[g200kg]

NWJS Version : 28.3
Operating System : Windows 64

Unfortunately, the issue #4464 is automatically closed, but I still hope to resolve this issue.

promise returned from requestMIDIAccess() with {sysex:true} will not be resolved nor rejected.
The code below does not show "OK" nor "Error" alert.

alert("requestMIDIAccess start");
navigator.requestMIDIAccess({sysex:true}).then(
    function(ma){alert("requestMIDIAccess OK");midiaccess=ma;},
    function(e){alert("requestMIDIAccess Error");},
  );
alert("requestMIDIAccess end");

In normal browser, this will display a dialog and wait for user's permission, but in NW it seems to be waiting without a dialog being displayed. I think NW should do the same behavior unconditionally as if choosing permission.

I can reproduce this issue on Linux/Windows with nwjs-sdk-v0.28.3.

This is fixed in git and will be available in the next nightly build.
