Current/Missing Behavior

Having a package.json of:

{
  "name": "nwjstest",
  "main": "index.html",
  "user-agent": "%webkit_ver"
}

Gives the following in navigator.userAgent:

537.36 (@0000000000000000000000000000000000000000)

Expected/Proposed Behavior

I expect it to show instead:

537.36 (KHTML, like Gecko)

Additional Info

• Operating System: Linux/MacOS, probably windows but had not tested it.

Looks like the zeroes are supposed to be the chromium git version.

[ayushmanchhabra]

Is the expected output exactly 537.36 (KHTML, like Gecko)?

[bluthen]

Yes, I hard coded it for me instead of using %webkit_ver

[ayushmanchhabra]

What is the last version that you know this was working? I feel like this could be an easy fix.

[bluthen]

We noticed it going from v0.78.1 -> 0.87.0

However trying v0.30.0, still shows the issue to me now. So maybe it has something to do with running on newer systems?

[ayushmanchhabra]

Shouldn't be the case since the characters after the @ should be the Chromium git commit. Maybe something in the build config changed?
