[Bug]: indented layout：the expansion and collapse of a node cause the positions of the other nodes to change.

### Describe the bug / 问题描述

缩进树布局（indented）下，节点折叠展开操作，引发图内节点位置变动；

配置：
```
class TreeNode extends Rect {
get data() {
return this.context.model.getNodeLikeDatum(this.id);
}
get childrenData() {
return this.context.model.getChildrenData(this.id);
}
getKeyStyle(attributes, container = {}) {
const [width, height] = this.getSize(attributes, container);
return {
...super.getKeyStyle(attributes, container),
width,
height,
size: [width, height],
stroke: "#000000",
fill: "#ffffff",
lineWidth: 1,
};
}
getLabelStyle(attributes) {
const [width, height] = this.getSize(attributes);
return {
text: "name",
fontWeight: 500,
fontSize: 14,
fill: "#333333",
lineHeight: 22,
textAlign: "right",
x: width / 2 - 11,
y: height / 2 - 14,
};
}

getCollapseStyle(attributes, container) {
if (this.childrenData.length === 0) return false;
const { collapsed } = attributes;
const [width, height] = this.getSize(attributes, container);
return {
fill: "#F6F6F6",
lineWidth: 1,
stroke: "#D9D9D9",
size: 14,
x: width / 2 + 7,
y: 0,
icon: true,
iconFill: "#666666",
iconText: collapsed ? "+" : "-",
iconFontSize: 16,
iconFontWeight: 600,
iconHeight: 8,
iconWidth: 8,
cursor: "pointer",
iconTextAlign: "center",
iconTextBaseline: "middle",
};
}
drawCollapseShape(attributes, container) {
const collapseStyle = this.getCollapseStyle(attributes, container);
const btn = this.upsert("collapse", Circle, collapseStyle, container);
if (btn && !Reflect.has(btn, "__bind__")) {
Reflect.set(btn, "__bind__", true);
btn.addEventListener(CommonEvent.CLICK, () => {
const { collapsed } = this.attributes;
const graph = this.context.graph;
if (collapsed) {
graph.expandElement(this.id);
} else {
graph.collapseElement(this.id);
}
});
}
}
render(attributes = this.parsedAttributes, container) {
super.render(attributes, container);
this.drawCollapseShape(attributes, container);
this.drawKeyShape(attributes, container);
}
}

register(ExtensionCategory.NODE, "tree-node", TreeNode);

const drawTreeGraph = data => {
graph = new Graph({
container: containerRef.value,
height: 380,
data: tData,
background: "#fff",
autoResize: true,
zoom: 1,
zoomRange: [0.6, 1.6],
node: {
type: "tree-node",
style: d => {
const style = {
radius: 4,
ports: [{ placement: "left" }, { placement: "right" }],
};
const size = [200, 32];
Object.assign(style, {
size,
});
return style;
},
},
edge: {
type: "quadratic",
style: d => {
const style = {
labelAutoRotate: false,
curvePosition: 0.5,
curveOffset: -19,
labelText: d.trace_data_count,
labelFill: "#666666",
labelBackground: true,
labelBackgroundFill: "#fff",
labelBackgroundShadowColor: "#fff",
};
return style;
},
},
layout: {
type: "indented",
direction: "LR",
dropCap: false,
indent: 300,
getHeight: () => 32,
preLayout: true,
},
behaviors: ["drag-canvas"],
autoFit: "view",
});
graph.render();
};
```

Start by reproducing the issue with the provided indented layout configuration and the custom TreeNode collapse handler, focusing on graph.collapseElement and graph.expandElement. Compare node positions before and after collapsing a node with many children; done means unrelated nodes retain their expected positions in the affected layout.
