Labels: framework,f: material design,has reproducible steps,P3,found in release: 3.19,team-text-input,triaged-text-input,found in release: 3.21

### Steps to reproduce

Place a PopupMenuButton as label of an InputDecoration object

### Expected results

When hovering over the PopupMenuButton it should be possible to click on it.

### Actual results

### Code sample

```dart
import 'package:flutter/material.dart';

void main() {
  runApp(const MainApp());
}

class MainApp extends StatelessWidget {
  const MainApp({super.key});

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: Scaffold(
        body: EconomicConditionsView(),
      ),
    );
  }
}

class EconomicConditionsView extends StatelessWidget {
  const EconomicConditionsView({
    super.key,
  });

  @override
  Widget build(BuildContext context) {
    return Column(
      mainAxisAlignment: MainAxisAlignment.center,
      children: List.generate(1, (index) => getPayerWidget(index)),
    );
  }

  Widget getPayerWidget(int index) {
    return InputDecorator(
      decoration: InputDecoration(
        enabledBorder: OutlineInputBorder(
          borderSide: const BorderSide(color: Colors.black),
          borderRadius: BorderRadius.circular(25),
        ),
        label: Row(
          mainAxisSize: MainAxisSize.min,
          children: [
            const Text('Hola'),
            PopupMenuButton<String>(
              itemBuilder: (context) {
                return List.generate(
                    5,
                    (i) => PopupMenuItem(
                        value: i.toString(), child: Text('Item $i')));
              },
            )
          ],
        ),
      ),
      child: Column(children: [
        Text('Adios'),
        Text('Adios'),
        Text('Adios'),
        Text('Adios'),
        Text('Adios'),
        Text('Adios'),
        Text('Adios'),
        Text('Adios'),
        Text('Adios'),
        Text('Adios'),
        Text('Adios'),
        Text('Adios'),
      ]),
    );
  }
}
