Problem description

Scrolling up through a program such as man in tmux leads to sympathetic scrolling in horizontally neighbouring panes. I cannot reproduce the issue over SSH or in terminal emulators running on Xvnc, so I assume the issue lies in Termux's terminal emulator.

Steps to reproduce the behavior.

Assuming tmux and man are installed and tmux has its default key bindings:

1. Start tmux.
2. Populate the pane with text, e.g. ls $PREFIX/bin.
3. Split the screen horizontally, i.e. CTRL-b %.
4. Run man tmux.
5. Scroll down by pressing DOWN a few times.
6. Scroll up by pressing UP a few times and observe that both panes scroll up simultaneously.

What is the expected behavior?

There should be no sympathetic scrolling.
