scrollBounce only bounces once for <webview>s

[javan]

• Electron version: 1.6.7
• Operating system: macOS 10.12.4

#9134 restored the scrollBounce preference (🎉), but it seems to only work once for <webview>s. Works ∞ times for browser windows. :)

To reproduce, apply these changes to the electron-quick-start app:

Weird, not sure why this is happening, can reproduce.

Quick update: This issue is still present in Electron 1.7 and 1.8.

I've just tried v2.0.0-beta.3 and the scrollBounce now works as expected for webview.

Seems like this is fixed, closing it out!

@codebytere seems there is a regression on Electron v3.0.2.
The scroll bounce only works once for the webview.
