Unable to reproduce on master. Possibly a race?

Seems fixed in this morning OTA. I suspect this was also a regression of bug 989198.

I'm pretty sure that this is caused by bug 989198. ;)

After bug 989198 is landed, all key events are propogating to both system app and the foreground app. That's why the web page is scrolled to the top.

Tzu-Lin is working on bug 1014418. Home keys and Volumes keys should be perserved by System app. No application is allowed to override the behaviour. So, after bug 1014418 is landed, no Home keys is dispatched to the foreground app, and this bug should be fixed.

In the meantime when bug 1014418 is getting reviewed, we will have a quick fix in System app to avoid home key being dispatched to applications. The quick fix will unblock bug 989198's landing.
