Changes to Typography.js aren't applied without server restart

[talolard]

Description

When following tutorial 2, line 240 implies we should be able to make a change to typography.js configuration and see the changes immediately.

This has not been working for us when following tutorial 2.

Additioanlly, we've tried "gatsby new " with the default starter, disabling layout.css and then configuring typography.js but the problem persists.

If we restart the gatsby server the new changes take effect.

Notably, if we look at the console output of the development server, nothing is emmited when we alter typography.js (where we configure typography). Perhaps it is being ignored by some watcher ?
Also, if we hotswap themes instead of hand crafted styled, the changes do take effect

Steps to reproduce

Follow the second part of the tutorial upto here.

Clear steps describing how to reproduce the issue. Please please please link to a demo project if possible, this makes your issue much easier to diagnose (seriously).

Expected result

When changing

src/utils/typography.js
import Typography from "typography"

const typography = new Typography({ baseFontSize: "18px" })

export default typography

to

src/utils/typography.js
import Typography from "typography"

const typography = new Typography({ baseFontSize: "24px" })

export default typography

Fonts should get bigger

Actual result

Everything stays the same
