Cursor does not get updated in grid mode

[RzvnB]

When you have multiple editors in a grid / split mode, the Vim mode is global - if you are in insert mode in a file in one region, when you move to a new region the mode will be the same. The cursor however, does not reflect this global mode - it reflects the last mode that was active when you were in that region.

OK, I confirmed it has a problem.
This problem is only cursor mode.
