 * There is a race condition problem because we read some data from props and some from the state.
 * The state is updated through a dispatch and is one render behind,
 * and so we have this weird one tick render where the displayedData in one selector have the old dataKey
 * but the new dataKey in another selector.
 *
 * A proper fix is to either move everything into the state, or read the dataKey always from props
 * - but this is a smaller change.
