Remove the non-null assertions.

placeholderHeader has type HTMLElement | undefined. Lines 120 and 121 suppress that case with !.

Use an explicit guard before calling within() or hasAttribute(). This gives a clear failure if the grouped-header shape changes.

Proposed fix 
     expect(placeholderHeader).toBeTruthy();
-    expect(within(placeholderHeader!).queryByRole('button')).toBeNull();
-    expect(placeholderHeader!.hasAttribute('aria-sort')).toBe(false);
+    if (!placeholderHeader) {
+      throw new Error('Expected a placeholder header');
+    }
+    expect(within(placeholderHeader).queryByRole('button')).toBeNull();
+    expect(placeholderHeader.hasAttribute('aria-sort')).toBe(false);

As per coding guidelines, “Avoid introducing new any, as unknown as, non-null assertions (!), or @ts-ignore to silence real type errors.”

120 - 121, Replace the non-null assertions on placeholderHeader in the
grouped-header test with an explicit guard that fails clearly when the element
is undefined, then call within() and hasAttribute() only after the guard.
