ReferenceArrayInput with AutocompleteArrayInput flickers and resets value on search when used with format and parse

[tomek3e]

What you were expecting:
When using AutocompleteArrayInput with a ReferenceArrayInput with parse/format options:

• the options list should not flicker
• the input value should not reset itself

What happened instead:

• the options list values flicker
• the input value resets itself

Steps to reproduce:

1. Open code sandbox
2. In the preview window, go to Comments list
3. Click on the icon to create a new comment
4. Select any value(s) in the Comments input
5. Enter any few characters

Environment

• React-admin version: 4.7.1

Reproduced, thanks

HI, I updated the CodeSanbox to react-admin 4.7.2 but the issue still persist with parse & format options.

Indeed!
I tried to make sure the format and parse props were not causing the re-render by moving them to a const, but the issue is still there.
The issue is not present however when you remove the format and parse props (which is what the PR #8599 fixed).

This actually makes sense inside a ReferenceArrayInput as it expects a specific format for the values (array of ids). @tomek3e, would you mind explaining your use case? Otherwise, I'll mark this as a documentation issue.
