Formatted errors does not show as formatted in cypress test runner

[Amitkahlon]

Current behavior

Cypress 10 new test runner omits formatting on errors such as new lines, tabs, etc.

Desired behavior

To be able to throw an error with formattings such as new lines, and tabs.
For example see how cypress dashboard prints the error below

Test code to reproduce

it.only('fail to format in test runner', { retries: 0 }, () => {
    Cypress.on('fail', (error, runnable) => {
      throw {
        ...error,
        message: `Failed to assert  event.\n\nExpectedValue:**${JSON.stringify(
          error.expected,
          null,
          4
        )}** \nActual args: **${JSON.stringify(error.actual, null, 4)}** \n
      `,
      };
    });

    cy.wrap({
      category: 'resources',
      name: 'action',
      label: 'copy_clipboard',
      target: 'keyboard',
      location: {
        title: 'favorites',
      },
      search: {
        clientSearchId: 'favorites',
        sessionId: 'favorites',
      },
      resources: {
        message: 'match(undefined)',
      },
      jsonData: {
        'action.trigger': 'command_bar',
      },
    }).should('deep.equal', {
      category: 'resources',
      name: 'action',
      target: 'keyboard',
      label: 'copy_clipboard',
      location: {
        title: 'favorites',
      },
      resources: [
        {
          id: 'UgfdGiIVw7NklNbHWSO-fw',
          list: 'favorites',
          appId: 'mockapp',
          type: 'mockapp:item',
          position: 0,
          linkId: '631483cead6377c7a8ef5c2e',
        },
      ],
      jsonData: {
        'action.trigger': 'command_bar',
      },
    });
  });

@Amitkahlon It does appear this used to work in 9.6.0 and no longer works in Cypress 10.7.0. Thank you for providing a reproducible example! I will make as a regression. That being said, I don't anticipate this issue will be picked up anytime soon. Would you be interested in contributing a fix to restore this behavior?

Yeah, that sounds interesting, can you point me in the right direction?
I will make my best attempt to fix it.

@Amitkahlon Great!! I did a little digging and I suspect it could be tied to this change: #22537 which was made to enhance the markdown formatting.

If it were me, I'd start with verifying the message is in the format you expected before we attempt to format it for the UI.

Thank you, I will give it a try this weekend
