TriggerKeyEvent - Backspace - Browser actively blocks from actually happening

Issue
---
When using the `triggerKeyEvent` with key of **Backspace** the browser actively blocks the interaction from happening on the input. Upon some research I discovered the browser event has a key of `isTrusted` when triggered by the test-helper that is set to false. But when manually inputing `backspace` during a pauseTest the `isTrusted` is set to true. Resulting in expected behavior.
