Re-enable React hydration error handling after Cypress fixes issue #27204

[mirhamasala]

Description

Cypress tests currently suppress React hydration errors as a workaround for a known Cypress issue. This should be revisited once the issue is resolved.

Code Location

packages/cypress/src/support/index.ts:8-9

Code Block

// Suppress React hydration errors in Cypress tests
// TODO: Revisit when Cypress fixes this known issue: https://github.com/cypress-io/cypress/issues/27204
Cypress.on('uncaught:exception', (err) => {
  if (
    err.message.includes('Hydration failed') ||
    err.message.includes('Minified React error #418') ||
    err.message.includes('Minified React error #423') ||
    err.message.includes('Unknown root exit status')
  ) {
    return false
  }
  return true
})
