[QGIS-Developer] point in polygon strikes again: big performance issue

[Delaz J]

Hi Jorge,

It doesn't explain nor fix the issue with your expression but mind 
trying /array_sum(overlay_contains('03-04-2021', 'Active'))/? No working 
QGIS around to test myself.

I don't remember if array_sum was introduced in 3.18 or master but 
overlay_** requires at least 3.16. Regards, Harrissou
