### 🐛 Bug description [Please make everyone to understand it]

### 📷 Step to reproduce

### 🏞 Expected result

### 🚑 Any additional [like screenshots]

* **G2Plot Version**: 2.4.17
* **Platform**: mac os 12.2.1

测试发现是配置了 layout: [{ type: "hide-overlap" }]，去掉 label 就全部显示了

Start with the linked CodeSandbox reproduction and inspect the chart configuration containing layout: [{ type: "hide-overlap" }]. Reproduce the behavior in G2Plot 2.4.17, comparing label rendering with and without that layout. Done means labels render correctly for multiple charts while the hide-overlap configuration is present.
