/**
 * Caution: If the mechanism should be changed some day, these cases
 * should be considered:
 *
 * (1) In `merge option` mode, if using the same option to call `setOption`
 * many times, the result should be the same (try our best to ensure that).
 * (2) In `merge option` mode, if a component has no id/name specified, it
 * will be merged by index, and the result sequence of the components is
 * consistent to the original sequence.
 * (3) In `replaceMerge` mode, keep the result sequence of the components is
 * consistent to the original sequence, even though there might result in "hole".
 * (4) `reset` feature (in toolbox). Find detailed info in comments about
 * `mergeOption` in module:echarts/model/OptionManager.
