[Docs]: Improve buttons sanitation explanation.

[WiXSL]

Because of #4574

👍

This conflicts with #4544 (already in master). Let me merge master into next and you'll change what needs to be changed.

[fzaninotto]

Done, please rebase

[WiXSL]

Done.

I don't understand, the previous code snippet already took care of sanitizing the extra props.

[Kmaschta]

Since we fixed the CreateButton props sanitation, and this Create and Edit views documentation already have a lot of tips and examples, I'm in favor of removing this tip.
It is not the purpose of React Admin to explain how Material UI components work ?

Also, this is an example of heavy customation, and the Create / Edit views documentation isn't really the good place for that. We have plenty of examples of customation on the demo IMHO

[WiXSL]

Actually the idea of #4574 was to remove #4544, But I didnt want to remove somebody elses work, so I improve it to a common use case that has the same problem.
A custom button could be created out of any library I just use material-ui as an example.

On second read, this is correct, thanks for the explanation and sorry for the questions. Can you just cancel the white space changes in the rest of the file?

[WiXSL]

They are not white spaces, they are zero width unicode characters (in this case \u200B).
I asume someone add them accidentally.
But I'll revert them back if you want, no problems.

Please confirm about this.

[fzaninotto]

You're right! How did you detect those? Some of us may have a bad setting in their IDE.

I'm using a plugin for IntelliJ-based IDEs.

Nice. I found this equivalent plugin for VSCode: https://marketplace.visualstudio.com/items?itemName=nhoizey.gremlins

Oh, I'll take note of that. Thanks.
