ConfigureChart Extension Function Trigger

Follow-up: The memory leak triggered by the Classic Chart update (anything that would trigger configureChart) was fixed in v8.0.6 but hasn’t yet made it into any version of v7.9. v7.9.13 was released shortly after v8.0.6, but this fix apparently did not make the cut. v7.9.14 will likely have it, and is expected in late April.
