Problem

AutocompleteInput sets filterSelectedOptions to true by default in its implementation.

However, the underlying MUI Autocomplete component defaults this prop to false (see implementation around line 436 in the MUI source).

This discrepancy leads to:

• Inconsistent behavior compared to MUI
• Unexpected filtering of selected options
• Confusing developer experience when relying on MUI defaults or typings

Solution

Explicitly set filterSelectedOptions={false} in AutocompleteInput so its default behavior matches MUI.

This keeps the prop overridable for users who want a different behavior.

How To Test

1. Render an AutocompleteInput
2. Select one or more options
3. Re-open the dropdown

This line was added in #7087, probably for a good reason. We need to investigate to understand the implications.

This issue was discovered while investigating the filterSelectedOptions default behavior inconsistency between react-admin and MUI.

I’ve opened a separate issue with a demo here:

Nothing prevents developers from changing this prop in user land. Besides, a discrepancy with MUI doesn't justify changing a behaviour that has been there for the past 4 years. We favor stability over new features.

So thanks for your PR, but we'll pass on this one.
