axe-core: Module not found: Error: Can't resolve 'crypto'

Discovered https://github.com/dequelabs/axe-core/issues/2840 along with two other warnings.

Upgraded to 4.1.4 and the issue referenced in that PR went away, but two remain (one of which seems related).

Product: axe-core

Expectation: build without warnings

Actual:

Looks like two warnings.

1. the “deoptimized styling”…

⠼ building... [Bundler][BABEL] Note: The code generator has deoptimised the styling of /Users/typeoneerror/Dev/pn/liberator/src/es-student/node_modules/axe-core/axe.js as it exceeds the max of 500KB.

Might be a non-issue.

1. This can’t resolve ‘crypto’ warning…

WARNING in ./node_modules/axe-core/axe.js
Module not found: Error: Can't resolve 'crypto' in '/Users/typeoneerror/Dev/pn/liberator/src/es-student/node_modules/axe-core'
 @ ./node_modules/axe-core/axe.js

I attempted setting

browser: {
  crypto: false
}

In package.json based on some related issues in other libs.

Motivation: no warnings

axe-core version: 4.1.4
via ember-a11y-testing: 4.0.2

Browser and Assistive Technology versions

For Tooling issues:
- Node version: 14.5.4
- Platform:  macOS 10.15.7
