Whether the condition customization feature is enabled for this visualization context. Enabled by default.
When the value is true, icon overrides applied through ConditionReference are honored. When the value is false, ConditionReference.Icon reads the condition's own icon instead of any override. The system preserves the overrides so they're honored again when the value is set to true. Throws ObjectDisposedException when you access this property after you call Context.Dispose on the context.
