Can't scroll output properly using mouse wheel when within a shh session

[jscheithe]

EDIT: This only happens when I'm within a ssh/mosh session.

Only a small number of output lines (like 10 or so) is accessible for scrolling using mouse wheel or scrollbar. When I'm on either end of the scrollable output, scrolling further cycles through the command history (just like the up and down arrow keys).

I can only make the whole output accessible by running a tmux session (which is not displayed correctly) inside the terminal.

I'm using Atom 1.41.0 on Ubuntu 18.04.3 . Ouput of apm list --installed --bare:
