Bug 1863194 - Do not terminate wheel transaction on browsing context change. r=hiro,smaug

Browse Source 
We should continue to use a wheel transaction for wheel events when the
browsing context changes from the current context. Avoiding the override
of the event target with the current wheel transaction can halt a page
scroll when the mouse moves over content in a different presentation
context.
