Modified element graphics are sometimes clipped

[pmconne]

Describe the bug
The temporary graphics drawn during a GraphicalEditingScope to represent modified elements are sometimes partially clipped.
Filed on behalf of @bbastings.

To Reproduce
Steps to reproduce the behavior:

Replace MoveElementTool in itwinjs-core\test-apps\display-test-app\src\frontend\EditingTools.ts with this (just so you don’t need to register another tool):

export class MoveElementTool extends Tool {
  public static override toolId = "MoveElement";
 
  public override async run(): Promise<boolean> {
    if (!IModelApp.viewManager.selectedView)
      return false;
 
    const imodel = IModelApp.viewManager.selectedView.iModel;
    if (!imodel.isBriefcaseConnection())
      return false;
 
    await startCommand(imodel);
 
    const id = "0x68b";
    const info = await basicManipulationIpc.requestElementGeometry(id);
    if (undefined === info)
      return false;
 
    const it = new ElementGeometry.Iterator(info);
    it.requestWorldCoordinates();
    let curveData;
 
    for (const entry of it) {
      curveData = { geom: entry.toGeometryQuery() as CurveChain, params: entry.geomParams };
      break;
    }
 
    if (undefined === curveData?.geom)
      return false;
 
    const result = CurveChainWithDistanceIndex.createCapture(curveData.geom).clonePartialCurve(0.9325068888021624, 1.0);
    if (undefined === result)
      return false;
 
    const props = await imodel.elements.loadProps(id) as GeometricElementProps;
    if (undefined === props.placement)
      return false;
 
    const builder = new ElementGeometry.Builder();
    builder.setLocalToWorldFromPlacement(props.placement);
 
    if (!builder.appendGeometryParamsChange(curveData.params))
      return false;
 
    if (!builder.appendGeometryQuery(Path.createArray(result.path.children)))
      return false;
 
    const dataEntry = { format: "flatbuffer", data: builder.entries };
    props.elementGeometryBuilderParams = { entryArray: dataEntry.data };
 
    await basicManipulationIpc.updateGeometricElement(props);
    await imodel.saveChanges();
    return true;
  }
}

Open the attached .bim file for editing in display-test-app and recall the attached saved view.
Key in dta edit then dta move element.
