Volar>Split Editors issues, is this a bug ?

[lincycode]

I set this option, and when I use this split function, it works. But when I try to revert to the original state, it reverts to the state of the right window("volar.splitEditors.layout.right" settings)

example:
the origin state

the split state(it works)

try to revert(not fully expanded, just like the window on the right)
