Page.navigate returns wrong frameId

[auchenberg]

The Page.navigate action should return the frameId ("Frame id that
will be navigated."). However, the Page.frameNavigated event is
sending a value that has absolutely nothing to do with the result from
the Page.navigate call. Instead, the frame ID that gets returned is a
value that looks to be increasing by 100 each time, so 1600, 1700,
etc, while the Page.navigate frameId result is always 5000.1.

The frameId returned by Page.navigate also seems to be a number, not a string as it should.
