创建连接桩markup使用rect标签，sourceAnchor配置的name不生效，线的起点难修改

[weimobcopilot09]

问题描述

创建连接桩，要自定义形状和大小，代码如下

		acc.push({
			markup: {
                                // tagName改成circle就生效，rect不生效
				tagName: 'rect',
				selector: 'body',
				style: {
					width: width,
					height: 20,
					stroke: 'transparent',
					fill: 'transparent',
					magnet: true,
					zIndex: 999999,
				},
			},
			attrs: {
                                // tagName改成circle
				rect: {
					magnet: true,
				},
			},
			label: {
				position: {
					name: 'right',
				},
			},
			args: {
				x: index === 0 ? 17 : acc[index - 1].distance + 17,
			},
			distance: distance,
			text: item.branchName,
			stylGroup: item.styleGroup,
			group: getPortsGroup(item),
			id: item.uuid,
		});

锚点配置如下

		sourceAnchor: {
			name: 'bottomRight',
			args: {
				// dx: 10,
				// dy: 6,
			},
		},
		connectionPoint: {
			name: 'anchor',
		},

预期行为

当使用rect标签时，连接桩的连接线的起点固定时左上角，必须指定dx/dy才能移动，指定为circle标签时，name配置可以生效
期望在使用rect标签时，也可以正确设置起点
