[Bug] Restore feature not properly resetting zoom feature

[rosenthalj]

Version

6.1.0

Link to Minimal Reproduction

All echarts official example demos with Zoom/Zoom Reset and Restore toolbox buttons, e.g: https://echarts.apache.org/examples/en/editor.html?c=line-aqi

Steps to Reproduce

1. Run any echarts example demo that has Zoom/Zoom Reset and Restore toolbox buttons
   -- for example: https://echarts.apache.org/examples/en/editor.html?c=line-aqi
2. Move the mouse over the chart
   -- Mouse icon will NOT display the zoom icon ("+")
   -- good
3. Click on the Zoom toolbox button and then move the mouse over the chart
   -- The Mouse icon will change to "+" the zoom icon
   -- good
4. Click and drag the mouse on the chart
   -- The chart will zoom in
   -- good
5. Click the Restore toolbox button
   -- Both the chartand the toolbox buttons/icons will reset
   -- good
6. Move your mouse over the chart
   -- Mouse icon is the "+" zoom icon
   -- bad

Current Behavior

The Restore toolbox button fails to fully restore when the Zoom button is pressed followed by pressing the Restore toolbox button

See the video listed below

echarts6.1ZoomAndRestoreIssue.mov

Expected Behavior

After pressing the Restore toolbox button, the chart and the toolbox buttons and the mouse icon are all restored to the original defaults

Environment

- OS: N/A
- Browser:  N/A
- Framework:  N/A

This issue can be reduced with Echarts Demo Examples.  The issue is independent of my development environment or the browser used in testing.

Any additional comments?

This is a regression in ECharts 6.1.0. The restore feature worked properly in ECharts 6.0.0.

In addition, if you add a listener for the zoom action:

myChart.on('datazoom', (params) => {
console.log("data zoom params", params);
})

You can see that the restore button is not properly resetting zoom.

The video listed below shows the following:

1). Adding the zoom listener to the official echarts example demo
2) Repeating the following steps
-- click the zoom button, zoom in using the mouse, click the restore
3). Every time 2) is repeated, the zoom listener results in an incremental increase of multiple console output

I reproduced this on the current official demo and captured the state transitions with browser automation.

Environment:

• URL: https://echarts.apache.org/examples/en/editor.html?c=line-aqi
• Rendered ECharts version from the iframe: 6.1.0
• Browser: headless Chromium via Playwright

Sequence used:

1. Hover chart before toolbox zoom: computed cursor on the canvas was grab.
2. Click the toolbox dataZoom/zoom icon and hover chart: cursor became crosshair.
3. Drag-select a zoom area: dataZoom range changed from about 95.088..100 to 96.306..99.066; one datazoom event fired.
4. Click the toolbox restore icon: dataZoom range reset to about 95.088..100.
5. Hover the chart again after restore: computed cursor on the canvas became crosshair again, not the original grab.

So the restore action appears to reset the zoom window, but it does not clear the toolbox dataZoom selection cursor state. I also checked the open PR search: there are related dataZoom PRs, but I did not find an open PR explicitly tied to #21644 or the restore-after-toolbox-zoom cursor state.

I have not isolated the root cause; this is just an independent reproduction/matrix to help triage the pending label.
