Yank copies text between selection end and bash input, not the selection itself

[abhemanyus]

Steps to reproduce:

1. Create some text to copy using curl https://example.org
   

2. Enter selection mode using 'Ctrl + Space + [' --> Navigate to start of line with HJKL --> Start selection using v --> Navigate until end of line.
   

3. Copy selection using Ctrl + Space + y. It shows "Line copied successfully at the bottom, but that was lost in the screenshot.
   

4. Paste copied text using Ctrl + Shift + v. Text does not matches selection at all.
   

Here's my ~/.config/tmux/tmux.conf:

set-option -sa terminal-overrides ",xterm*:Tc"
set -g default-terminal "xterm-256color"
set -g mouse on
set -g set-clipboard on

unbind C-b
set -g prefix C-Space
bind C-Space send-prefix

# Vim style pane selection
bind h select-pane -L
bind j select-pane -D 
bind k select-pane -U
bind l select-pane -R

# Start windows and panes at 1, not 0
set -g base-index 1
set -g pane-base-index 1
set-window-option -g pane-base-index 1
set-option -g renumber-windows on

# Use Alt-arrow keys without prefix key to switch panes
bind -n M-Left select-pane -L
bind -n M-Right select-pane -R
bind -n M-Up select-pane -U
bind -n M-Down select-pane -D

# Shift arrow to switch windows
bind -n S-Left  previous-window
bind -n S-Right next-window

# Shift Alt vim keys to switch windows
bind -n M-H previous-window
bind -n M-L next-window

set -g @plugin 'christoomey/vim-tmux-navigator'
set -g @plugin 'catppuccin/tmux'
set -g @plugin 'tmux-plugins/tmux-yank'

set -g @catppuccin_flavour 'mocha'

run '~/.tmux/plugins/tpm/tpm'

# set vi-mode
set-window-option -g mode-keys vi
# keybindings
bind-key -T copy-mode-vi v send-keys -X begin-selection
bind-key -T copy-mode-vi C-v send-keys -X rectangle-toggle
bind-key -T copy-mode-vi y send-keys -X copy-selection-and-cancel

bind '"' split-window -v -c "#{pane_current_path}"
bind % split-window -h -c "#{pane_current_path}"

Okay, while Ctrl + Shift + v just pastes gibberish, Ctrl + Space + y works fine.
Still gonna wait for a reply before I close this, though.

This is quite old, sorry... How did to paste with Ctrl + Space + y? It just says "Line copied successfully" again, even though I am not in the visual mode anymore.

Also, isn't the failure of Ctrl + Shift + v because the tmux clipboard is separate from the system clipboard?
