Cursor Error when switch window

[HsunGong]

General information

iterm 3.4.3
zsh5.8
os macos
tmux 2021

Basic examination

When open 2 terminal window in tmux,
In first terminal, we use zsh with vi-insert mode;
In the second terminal, we then open a vim window;
Found that the vim cursor is changed based on the first window, shown in the picture.

Expected behavior

In vim window, we want block cursor rather than underline/beam.

reproduction

1, ZVM_INSERT_MODE_CURSOR=$ZVM_CURSOR_BEAM or $ZVM_CURSOR_UNDERLINE

2, tmux with 2 panes in ONE window.

3, in pane ONE: toggle insert mode in zsh-vi-mode

4, in pane TWO: use vim to open a file(no mode requirements<INSERT/NORMAL> is ok).

5, see vim file: the cursor is changed to BEAM or UNDERLINE as the picture.

6, if does not reproduced, use this:

enter pane ONE: enter insert mode(to get underline/beam)
reenter pane TWO with vim: find underline/beam in vim.

@HsunGong, this issue is the same as another issue #11.
