Not show prefix after source a new colorscheme

[RoachZhao]

Hi, there. This plugin work fine until I change the colorscheme of tmux by tmux source-file new_scheme.

My setting about tmux-prefix-highlight as below:

set -g @plugin 'tmux-plugins/tmux-prefix-highlight'

set -g @prefix_highlight_fg 'colour00'
set -g @prefix_highlight_bg 'red'
set -g @prefix_highlight_show_copy_mode 'on'
set -g @prefix_highlight_copy_mode_attr 'fg=colour00,bg=colour05,bold'
set -g @prefix_highlight_prefix_prompt 'PREFIX'
set -g @prefix_highlight_copy_prompt 'COPY'

And when I run tmux it works, a screenshot show the prefix after press <c->（my tmux prefix） as below:

But if I change to a new colorscheme like: tmux source-file ~/.tmux/tmuxline/edge-dark.tmux.conf

There is no PREFIX on the right statusline after I press <c->

And the content of edge-dark.tmux.conf as below:

Found reason as colorscheme reset statusline.
