[Bug]: resize行为异常

### Describe the bug / 问题描述

以下代码会导致画布异常。
```javascript
size.value = _size
graphParent.value?.setAttribute('style',`width:${size.value[0] + 40}px;height:${size.value[1] + 40}px`)
refContainer.value?.setAttribute('style',`width:${size.value[0]}px;height:${size.value[1]}px`)
GraphEditor.graph.resize(size.value[0],size.value[1])
```
可以重置画布大小，但是不能添加图元了，也不能滚轮缩放画布了，都也没报错

Start from the GraphEditor.graph.resize call and the related size, graphParent, and refContainer updates shown in the report. Reproduce the state after resizing where adding elements and wheel zoom stop working, then trace the resize path. Done means resizing preserves both element insertion and canvas wheel zoom; no reproduction link or test file is provided.
