JSC_INEXISTENT_PROPERTY_WITH_SUGGESTION is hidden if the inexistent property is set in unrelated code. about closure-compiler

I suspect this is happening because by doing SGlobal.scaleT = 4; inside ZoomManager.prototype.neverCalled you have created a property named scaleT. Hence it's no longer an inexistent property, i.e. the compiler sees that a property with that name exists somewhere in the code. Hence the inexistent property error is not reported by closure compiler and this seems WAI to me.

Furthermore, if you change the neverCalled method to have a "use" of the inexistent property, then the compiler correctly complains at both use-sites of the inexistent property.

ZoomManager.prototype.neverCalled = function() {
	this.m_x = SGlobal.scaleT;
};

Will discuss this in the internal bug triage meeting and update again.

Closing as WAI per my comment above.
