While editing a file, Google Web Designer uses -webkit prefixes. However, when you publish your content, the publish dialog allows you to specify additional vendor prefixes (or no prefixes) in the output so the content works in different browsers.
I hope this helps.

Google Web Designer (GWD) uses the WebKit HTML rendering engine inside the application's workspace and reports the styles that are actually applied to the content during editing.

1. This tool can't produce cross-browser output
2. This tool includes some rendering engine-specific markup to solve cross-platform issues.
1 is unlikely and 2 is benign.
Meaning what? Google isn't directly involved with WebKit anymore and can't make them implement standards.
Microsoft and FrontPage did the exact same thing back in the days.
This is like IE4/Netscape Communicator days all over again, except now with more than two dominant browsers...
