React v16.x reports errors when using boolean operators for conditional
classnames and requires that you instead use ternary style conditional
clauses.
The final size of renderer.prod.js is about 4.75mb. 2.35mb of this comes
from react-icons.
Update the react icon imports to import only the specific icons that we
use. This reduces the final size of renderer.prod.js by about 50%
