Some icons are not displayed in prod mode

[dopenguin]

Describe the bug
Some icons are not displayed when the client is built as seen on e.g. https://dataport.github.io/polar/live/.
The issue does not exist in dev-mode.

Expected behavior
I'd assume that all used icons that are elligible material symbols are rendered in production builds.

@dopenguin Icons are correctly rendered, e.g. on https://dataport.github.io/polar/next/. Is the problem still occurring?
