**TITLE**
[Bug] The selected area echoes abnormally
**BODY**
### Version
5.5.0
### Link to Minimal Reproduction
None at the moment, some geo data cannot be displayed.
### Steps to Reproduce
I found a problem. I want to implement the map drill-down function. The code
is implemented as follows. First, the default map data [map] is loaded, and
then the click event is bound. When processing the click event, switch the map
to map2, and then call goback to reset the options. When, the effect is not as
expected
var options = {
tooltip: {},
geo: {
map: 'map',
regions: [],
},
series:[
{
type: "map",
geoIndex: 0,
data: [],
}
],
};
onMounted(async () => {
mapData = ...;
mapData2 = ...;
mapDom = document.getElementById('map');
myChart = echarts.init(mapDom);
mapData = await util.getGeoData();
echarts.registerMap("map", mapData);
myChart.setOption(options);
myChart.on('click', e => {
echarts.registerMap("map2", mapData2);
options.geo.map = "map2";
myChart.setOption(options);
})
})
function goback() {
echarts.registerMap("map", mapData);
options.geo.map = "map";
myChart.setOption(options);
}
### Current Behavior
After goback is triggered, the following problems occur
1. I found that the area I clicked for the first time was not selected, but
when I moved the mouse over the area I clicked last time, it was selected
again, and after leaving the area, the selected state will not disappear.
2. Later I tried setting options and specified notMerge as true. When I
returned to the previous step and repeated step 1, it would still not be
selected, but it would not be selected when sliding over the selected area.
3. When there is no series in options, the above situation will not occur,
and the selected area will not be recorded.
### Expected Behavior
1. When returning to the previous step, you can select the area clicked last
time.
