Backlink arrow displays incorrectly on mobile

[zxhd863943427]

Is there an existing issue for this?

• I have searched the existing issues

Can the issue be reproduced with the default theme (daylight/midnight)?

• I was able to reproduce the issue with the default theme

Could the issue be due to extensions?

• I've ruled out the possibility that the extension is causing the problem.

Describe the problem

在移动端打开反链dock，使用单个展开和全部展开都无法正常展开并显示内部内容

我发现这个问题是因为我在尝试使用/api/ref/getBacklink api接口，但是返回结果很奇怪，backlink的项里存在block和children两个返回值，block里缺乏面包屑，children里缺乏引用所在内容块的id，只有父元素的id，所以我想看看思源自己是怎么处理的，结果发现思源自己也是异常的。

Expected result

在移动端打开反链dock，可以正常展开并显示内容。

改进/api/ref/getBacklink api接口的返回
