// this is because in the case of mod selection in solo gameplay, a user selection of a mod can actually lead to deselection of other incompatible mods.
// to synchronise state correctly, updateBindableFromSelection() computes the final mods (including incompatibility rules) and updates SelectedMods,
// and this method then runs unconditionally again to make sure the new visual selection accurately reflects the final set of selected mods.
// selectionBindableSyncInProgress ensures that mutual infinite recursion does not happen after that unconditional call.
