Buttons/page re-renders multiple times on page load

[jfrankl]

Description

I added a console.log on the geounit switching buttons. I noticed that when the map editing view loads, each of these buttons gets rendered/re-rendered five times. This might be related to #285, but I wanted to call it out in case it's separate. I thought this was interesting because it happens on page load.

Steps To Reproduce

1. Add a console.log or similar to the geoLevelOptions.map loop
2. Load a project
3. Look in your console

Expected behavior

I'd expect these buttons to render once.

Actual behavior

They each render five times, it appears.
