Steps to reproduce

Steps:
There are two live examples:

• Example 1 (no isRowSelectable): https://stackblitz.com/edit/q7x7x1ea?file=src%2FDemo.tsx
• Example 2 (with isRowSelectable): https://stackblitz.com/edit/ddumkzun?file=src%2FDemo.tsx

1. Open Example 1 and click the “Select all” checkbox in the DataGrid header.

• Result: Selection is instantaneous; the UI remains responsive.

2. Open Example 2 and click the “Select all” checkbox in the DataGrid header.

• Result: The screen freezes and becomes unresponsive.

Notes:

• Both examples are based on the official MUI X Data Grid demo.
• The only change in Example 2 is adding isRowSelectable={() => true} to the DataGridPro component.

Current behavior

When selecting all rows in DataGridPro with a large dataset (e.g., 1000+ rows) and using the isRowSelectable prop, the screen freezes and becomes unresponsive.

Expected behavior

Selecting all rows should be more performant when the isRowSelectable prop is provided, just as it is when no isRowSelectable prop is used.

Context

We are using DataGridPro with large datasets (1000+ rows) and need to control row selection dynamically using the isRowSelectable prop. However, when users attempt to select all rows, the entire app freezes for 10+ seconds.
