Firefox UI Elements Too Small in Wayland/Sway, Main Menu is Cut Off

I'm having a couple of issues with the Firefox main menu and other UI elements.

Issue #1:
When I open the menu, the bottom portion is cut off. The lower options can only be reached by scrolling. This problem is not present when running Firefox with the same hardware and graphics drivers under X. It started when I began using Wayland/Sway. I haven't found any workarounds.

Issue #2:
After the laptop wakes from sleep, the menu shrinks to half its normal size. The clickable area remains the same, so I have to guess where the option are. This issue isn't limited to the main menu. All dynamic UI elements are affected. If I create a new Firefox window, the UI elements are again "right-sized". Moving the tabs over to the new window allows me to regain control. Restarting Firefox also works. This problem started when I modified my Sway config to work with an external monitor.

- Sway 1.5.1
- Wayland 1.18.0
