Is there an existing issue for this?

  To pick up a draggable item, press the space bar. While dragging, use the arrow keys to move the item. Press space again to drop the item in its new position, or press escape to cancel.

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

Could the issue be due to extensions?

Describe the problem

1. 如果使用快捷键"新建子文档名为"时,当前行是空段落,那么在创建完引用时会选中当前文档所有块

2. 如果创建的子文档已经存在,那么会使用那个文档,而不是创建新的同名文档 ,即便是未命名文档 (Untitled),也会如此

建议: 如果同名子文档已经存在,则询问用户是使用已存在的,还是创建新的

两个子文档同名的场景举例:
一个文档有两个公式, 这两个公式各自都有一个对应的 "推导" 文档,
