Do not use TMUX_WRAP for DECSCUSR sequence

Browse Source 
Wrapping it will send it to the terminal "directly", which might change the
cursor of another pane, e.g. when starting Neovim and changing to
another pane directly.

tmux has a terminfo extension (Ss/Se) to handle and translate the
DECSCUSR sequences internally.  This can be controlled through
`terminal-overrides`, but does not appear to be able to handle the
uncommon sequences for Konsole.
