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.
