Breaking keywords in multi window configs

[DanBmh]

I have a strange error of a normal word combination breaking the correct behavior in multi-window configurations.
If my config contains the word -time, the second window doesn't work correctly anymore.
In my case I wanted to open a file which included -time in its filename.

I could replicate it with the following minimal example:

tmuxp load tmuxp_test.yaml

session_name: testerror
windows:

  - window_name: 'win1'
    layout: tiled
    panes:
      - 'echo "A" && sleep infinity'
      - 'echo "B" && sleep infinity'
      - 'echo "C" && sleep infinity'
      - 'echo "D" && sleep infinity'

  - window_name: 'win2'
    layout: tiled
    panes:
      - 'echo "E" && sleep infinity'
      - 'echo "-time" && sleep infinity'
      - 'echo "F" && sleep infinity'
      - 'echo "G" && sleep infinity'

Instead of the expected printouts in each pane, the last pane of the first window contains:

echo "D" && sleep infinity
#@###:~$  echo "D" && sleep infinity
D
echo "-time" && sleep infinity

so it also has the problematic command of the second window. The first three panes of the first window only have the normal first 3 lines.
The second window prints the other 3 echos, but has executed an empty command in the second pane (instead of echoing "-time").

This also only happens in multi-window settings, if you comment-out the first window part, all of the second's window panes print correctly, the one with -time as well.
It took me a while to point it down to the string itself, but for my main problem I can workaround it by just renaming my file.

The problem is the same as in: #915

Can be solved by updating tmuxp (the apt version seems to be out-of-date, but installing the pip version with pipx works).
