E2E failure appears to be genuine, also happening on #2870 (dependabot PR to update webpack)

  1) Translations
       should display translated content for a supported language:
     AssertionError: Timed out retrying after 4000ms: Expected to find content: '关于' within the selector: 'h1' but never did.
      at Context.eval (webpack:///./cypress/e2e/common/i18n.cy.js:24:7)

Not reproduced locally in dev mode, testing production build now.

[AlanGreene]

Reproduced locally with production webpack build. It's a known issue with the latest webpack release: webpack/webpack#17042

This breaks our loading of the translations:

dashboard/src/containers/App/App.js

Lines 119 to 120 in 488c2c8

	const { default: loadedMessages } = await import(
	/* webpackChunkName: "[request]" */ `../../nls/messages_${targetLocale}.json`
