Tiptap: Safari crashes on input

[winterdedavid]

Describe the bug
The most recent desktop version(s) of Safari (13.0.1 and also 12.1) seem to completely crash (permanent spinning beach ball) when inputting the first character into the tiptap editor, requiring a force quit of Safari itself. The Javascript console itself shows no error logs when this happens. We originally noticed this in our own application, but it appears to also occur on the demo editor on the tiptap homepage, identical behaviour.

Steps to Reproduce / Codesandbox Example
Steps to reproduce the behavior:

1. Go to https://tiptap.scrumpy.io/
2. Input some text in the demo editor

Environment

• OS: macOS Mojave
• Browser Safari
• Version 13.0.1 (and apparently also 12.1)
• Mobile / Desktop: Desktop (confirmed that it does not occur on mobile)

I can confirm the behaviour.

I also checked the CPU and memory usage and both are low.

__Environment__

• OS: macOS Mojave 10.14.6
• Browser: Safari 13.0.1 (14608.2.11.1.11)

omg… this took me a long time. the crash was caused by font-family: -apple-system; on the demo page. it's a safari bug 🤦‍♂️

Big thanks for the quick solution @philippkuehn ! ;) We had a real hard time figuring out what the root cause would be..
