Numlock not working in cosmic terminal

[guusec]

When numlock is enabled cosmic terminal still treats 8, 6, 4, and 2 as arrow keys, 7 and 1 jump to the beginning and end of lines, 3 enters a ~ character, and 5 works as intended. When switching to xterm, my numpad works fine, same with every other application. It's just cosmic terminal.

[git-f0x]

This is the same issue as pop-os/cosmic-epoch#1193, and affects all rebased apps (in text input boxes, 5 also doesn't work).
