### Steps to Reproduce

1. Click the zoom button in the toolbox area.
2. Left-clicking directly on the chart will cause the cursor icon to change to a gesture state.

### Current Behavior

Clicking the cursor will change it to a gesture state.

### Expected Behavior

Normally, it should be in the zoom cursor state.

### Environment

```markdown
- OS: Mac 26.2 (25C56)
- Browser: Chrome 151.0.7922.76
- Framework:
```

### Any additional comments?

_No response_

Start with the linked minimal reproduction in the ECharts example editor and reproduce the zoom-button interaction in the stated Chrome environment. Inspect the toolbox zoom interaction and cursor state; the work is done when clicking the chart after enabling zoom keeps the cursor in the expected zoom state rather than changing to a gesture state.
