Non-Interaction option has a bug.

When Non-Interaction option is true, all GA events are sent with interaction hit.

Probably, Frontend javascript has two bugs.

1) ga_options.scroll_elements has “bounce” field. But reffered “non_interaction” field.
2) parseInt function failed to parse boolean string. (e.g. “true” -> NaN)
