[Compose] Cannot add several SymbolLayers at the same locations

[JulienNevo]

Environment

• Android OS version: 11.0
• Devices affected: Xiaomi MI 11 and emulators
• Maps SDK Version: 11.4.0

Observed behavior and steps to reproduce

Adding two SymbolLayer with icon/and images will not stack up, items of one or another layer being chosen seemingly randomly.

SymbolLayer(
        layerId = "layer1",
        sourceState = displayedItems,
        iconImage = IconImage("mb_image1"),
        iconAnchor = IconAnchor.BOTTOM,
)
SymbolLayer(
        layerId = "layer2",
        sourceState = displayedItems,
        iconImage = IconImage("mb_image2"),
        iconAnchor = IconAnchor.CENTER,
)

I would like to show (or not) parts of items according to business rules, but I cannot currently do that, as it seems items located at the same locations are visually exclusive.

Expected behavior

All items at one location should show.

Hey @JulienNevo can you try with setting iconAllowOverlap and iconIgnorePlacement to true?

[JulienNevo]

Thanks for your answer. Yes, iconIgnorePlacement works rather fine, but the problem is that zooming out will not remove the symbols of a layer when they overlap between them. So I get a very messy group of the symbols...
