[Data collection] Some Predefined sample sites don't render

[jo-spek]

Created this survey with 25 pre-defined sites: https://ground.openforis.org/en/survey/au4T5os5gRtyOEMGCYnX
Sites: https://drive.google.com/file/d/1pPd3T5FXUjVAqKdAFGquuT2yY0TfUUzh/view?usp=sharing (no sensitive data).

In Build 0.3.1 - 2025-12-01, zooming in from the green grouping dots, some of the polygons are properly shown, but for some, only the grouping dot stays and doesn't change and the desired polygon does not appear.

@kenstershiro @gino-m
Does this require a parallel bug report for ground-platform?
Please assign as you see fit.

@jo-spek I think this ticket is enough for now, unless the Android team find the cause is with the data and not just the map rendering. I've put it in the To Do list for next iteration for now, @andreia-ferreira or @anandwana001 this is a fairly high priority P1
