fix(WidgetManager): cross-renderer widget usage

[floryst]

Context

Widgets should not remain in an active state if interaction occurs outside of the containing renderer.

An alternative to deactivating all widgets in the widget manager in such a scenario is to filter out interaction events at the widget level that are not targeting the widget's renderer. Such an alternative has the benefit of allowing widgets to remain active for future in-renderer interactions.

I'm still figuring out if this change might break any existing expectations.

Addresses #3144.

Results
