"CannotAddLayerException: Cannot add layer twice" when removing a layer **by id** and adding it again

Device

Galaxy Z Fold 6, Pixel 8 Pro, Simulator

What happened?

When removing a layer by ID and adding it again, CannotAddLayerException is thrown. I expect it to work the same as removing a layer by reference (style.removeLayer(style.getLayer("water")!!))

Steps to reproduce

This throws the exception:

map.setStyle(
    Style.Builder().fromUri(...)
) { style ->
    val waterLayer = style.getLayer("water")!!
    style.removeLayer("water")
    style.addLayer(waterLayer)
}

This does not throw the exception:

map.setStyle(
    Style.Builder().fromUri(...)
) { style ->
    val waterLayer = style.getLayer("water")!!
    style.removeLayer(waterLayer)
    style.addLayer(waterLayer)
}

Renderer

OpenGL (choose this if you are unsure)
