RaiseEvent in control event handler targets source control and can recurse until stack overflow

RaiseEvent inside a Studio-generated control event handler can raise the control's event instead of the containing object's event.

Reproduction:

• Add an Opening() event to a Button on a window
• Create an event definition in this button called Opening
• Add RaiseEvent Opening to the Opening event of the Button
• Run the program

Expected: RaiseEvent Opening should raise Window1.Opening.

Actual: It raises Button1.Opening again, recursively invokes Button1_Opening, and eventually fails with:

Runtime error: Stack overflow (too many nested calls).
