noRefCheck functions on the Show Code

Describe the bug I found something weird when reading the code generated on Storybook, that is every function that I didn’t define, shows up as noRefCheck. Even though if I set it manually as undefined.

But no, that’s just a background, and I believe that issue might have to do with the react-element-to-jsx-string. The actual issue, is that the first function is always written as () => {} while the rest functions would be written as function noRefCheck() {}. Now that’s pretty weird behaviour IMO. Please take a look at this built-in example (?) below

Now… isn’t that code should be like this below?

<Header
  onCreateAccount={() => {}}
  onLogin={() => {}}
  onLogout={() => {}}
  user={{
    name: 'Jane Doe'
  }}
/>

it looks more pretty.

To Reproduce I don’t think I need to create a repo for this. I just simply:

1. Run npx create-react-app
2. Run npx sb init
3. Run npm run storybook
4. Wait, and open EXAMPLE > Header

Additional context I think I found the culprit, just replace the replace with replaceAll. If you allow, I can create a PR to fix this including adding a new unit test to cover this one. wdyt?
