Uncaught TypeError: Cannot read property 'value' of null

Ran into an interesting case with the latest rrweb:

Uncaught TypeError: Cannot read property 'value' of null
    at MutationBuffer.emit (rrweb.js:1932)
    at MutationBuffer.processMutations (rrweb.js:1826)
    at MutationObserver.nrWrapper (design-projects:26)

How to reproduce:

1. Go to https://www.betabrand.com/design-projects, open chrome console
2. Paste into console" var script = document.createElement('script'); script.type = 'text/javascript'; script.src = 'https://cdn.jsdelivr.net/npm/rrweb@latest/dist/rrweb.js'; document.head.appendChild(script);
3. Paste into console: rrweb.record({ emit: () => {} })
4. Open navigation, go to Yoga Denim.
5. See uncaught errors in console

The site is using angular-js under the hood.

I added some debugging code to the library, and I think the suspicious element (that is later being read as null) is shown in the screenshot (1224), it matches with the index of addList element being null.

I’ll check this tonight.

@macobo I think I’ve found the root cause. You can have a try on v0.9.14.
