ConsoleMessage type and text not interoperable between Chrome and Firefox

Steps to reproduce

Tell us about your environment:

• Puppeteer version: 5.2.0
• Platform / OS version: macOS 10.15.5
• Node.js version: v10.16.3

What steps will reproduce the problem?

Please include code that reproduces the issue.

'use strict';

const puppeteer = require('puppeteer');

async function main() {
  for (const product of ['chrome', 'firefox']) {
    const browser = await puppeteer.launch({product});
    const page = await browser.newPage();
    await page.goto('about:blank');
    const msgPromise = new Promise((resolve) => {
      page.on('console', resolve);
    });
    await page.evaluate('console.log("message")');
    const msg = await msgPromise;
    console.log({
      product,
      type: msg.type(),
      text: msg.text(),
      args: msg.args(),
    });
    await browser.close();
  }
}

main();

Output from running the above is:

{ product: 'chrome',
  type: 'log',
  text: 'message',
  args:
   [ JSHandle {
       _disposed: false,
       _context: [ExecutionContext],
       _client: [CDPSession],
       _remoteObject: [Object] } ] }
{ product: 'firefox',
  type: 'verbose',
  text: [ 'message' ],
  args: [] }

What is the expected result?

The msg.type() and msg.text() should be the same for Chrome and Firefox, to make it possible to use console messages without switching on which product is under test.

What happens instead?

• Chrome: msg.type() is “log” and msg.text() is “message”.
• Firefox: msg.type() is “verbose” and msg.text() is an array with a single item “message”

msg.args() is also different, but I don’t know what it should be, and am not using it myself.

Just checked and there is no difference anymore between Chrome and Firefox. Both output the following:

{
  product: 'test',
  type: 'log',
  text: 'message',
  args: [ JSHandle {} ]
}

Thanks @whimboo!
