Possible regression: Error after closing the pane

[tscolari]

Hello there, I think there is a regression at some recentish change 🤔
I use vimux as the strategy for nvim-neotest, and up until recently the behaviour it presented was, for example:

- run some tests
- it would open a pane, and run the tests there
- I could close the pane
- run again some other tests
- it would open another pane

Now, what is happening is that when I close the pane, if I try to run the command again I'll get this error from vimux for example:

Error detected while processing function test#run[27]..test#execute[23]..test#shell[19]..test#strategy#vimux[2]..VimuxClearTerminalScreen[2]..VimuxSendKeys[2]..VimuxTmux[8]..function test#ru
n[27]..test#execute[23]..test#shell[19]..test#strategy#vimux[2]..VimuxClearTerminalScreen[2]..VimuxSendKeys[2]..VimuxTmux:                                                                    
line    8:                                                                                                                                                                                    
E605: Exception not caught: Tmux command failed with message:can't find pane: %71^@

Is this intended?
I've been trying to find out what could be causing this, any help will be appreciated.
