26.1版本无法修改已有会话分组名称 Version 26.1 cannot modify the name of an existing session group

26.1版本会话分组重命名,会自动变成添加新的上级分组,原会话分组名称依旧变成子会话分组,测试25版本正常,期待大佬修正.In version 26.1, the session group is renamed, and it will automatically become a new parent group. The original session group name will still become a sub-session group. The test version 25 is normal. I look forward to the big guys correcting it.

Reproduce renaming an existing session group in version 26.1 and compare the same action in version 25. Trace the session-group rename flow from that UI action; done means renaming changes the existing group name without creating a new parent group or retaining the old name as a child group.
