@MarcinMr looks good. Ready to approve once you address my comment about the ssr-server file. Thanks!

Also, I updated this branch with the latest from feature/bolt-5-0 to fix the failing Travis build. It needed the new chromedriver.

@MarcinMr why were these lines below removed? They don't seem to be related to dropdown.

This whole ssr-server package is unused to it's no big deal, but if these weren't intentionally removed let's revert this part of the PR.

Hmm I couldn't remind myself how and why I removed those lines of code... I tried to restore it but every time I save the file, the code removes itself. I checked on a master and it happens either for that file. It looks like this:

the code is grayed out a littlebit

and when I hover over it, there is an info msg that the code is unreachable

Quick fix proposes deleting that code.

Could you please explain why it happens and how can we solve it?

Here is how it behaves on save:

Ah, ok. It is in fact unreachable code and VS Code is automatically removing it.

Anything after a return statement will not run. For example:

myFunctionA() {
  console.log('this will run');
  return 'foo';
  console.log('this will never run');
}

myFunctionB() {
  if (option) {
    return 'foo';
  }
  console.log('this will run only if `option` is falsy');
}

In this file, there is a return statement above the lines you removed, so these lines will never run.

This is fine to remove in this PR 👍
