Regression Quill 2.0.0 ( Quill.register)
With ReactJS On Version 2.0.0 Quill.register is not a function
That works with Quill 2.0.0-dev.4
To reproduce, i have created two codesanbox :
Quill 2.0.0-dev.4: (Version that works) https://codesandbox.io/p/sandbox/quill-2-0-0-dev-4-w2sfmd
Quill 2.0.0 (Version with error) https://codesandbox.io/p/sandbox/quill-2-0-0-33qn9p
react-quilljs is a thrid-party library and looks like it doesn't support Quill 2.0 yet. In fact you don't need a library in order to use Quill in your project. Here's an example: https://quilljs.com/playground/react
For the issue with react-quilljs, I think the reason is that Quill 2.0.0 is an ESM package whereas dev.4 is a CJS package, and react-quilljs may not support ESM correctly.
