AutocompleteInput: inconsistent input update behavior with filterSelectedOptions={false} compared to MUI

[540792740]

What you were expecting:
When using filterSelectedOptions={false}, selecting a filtered option should immediately update (autocomplete) the input value — consistent with MUI Autocomplete behavior.

What happened instead:
In AutocompleteInput (react-admin):

• After selecting an option
• Then deleting the last few characters of the input
• Selecting the same option again

👉 The input does not update immediately
👉 It only updates after the input loses focus (blur)

This results in a delayed and inconsistent user experience.

In contrast, MUI Autocomplete updates the input value immediately upon selection.

Steps to reproduce:

1. Render two components side by side:

• react-admin AutocompleteInput
• MUI Autocomplete

2. Set filterSelectedOptions={false} on both
3. Perform the following steps:

• Select an option (e.g., “Apple”)
• Delete the last 1–2 characters from the input (e.g., “Appl”)
• Click the same option again from the dropdown

4. Observe behavior:

• react-admin: input does not update until blur
• MUI: input updates immediately

Temporary workaround: add blurOnSelect={true}

Although now the selected text is not chopped, this workaround is suboptimal for keyboard only user because the input is blurred.

A proper fix may need to check if reason===selectOption in onInputChange callback, and then call the setFilterValue() function
