Clicking on a link in a Flutter Web page using an accessibility service causes the page to reload

[math1man]

Steps to reproduce

1. Copy the repro project into DartPad and run it
2. Enable accessibility in Flutter
3. Use an accessibility service or a mouse to click on the button

Expected results

Nothing should happen, similar to clicking on the button with a mouse without enabling accessibility.

Actual results

The UI performs a screen transition as if it were some sort of navigation. I believe this symptom is also what is causing the reload in our app.

Code sample

Code sample

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        body: Center(
          child: InkWell(
            onTap: () {},
            child: Semantics(
              link: true,
              child: const Text('Hello, World!'),
            ),
          ),
        ),
      ),
    );
  }
}

Thanks for the bug report @math1man
I tried the code sample using latest stable (3.19.5) running on web with accessibility enabled but was unable to see the page getting reloaded.

I can't access it, so not sure which flutter version are you on. If above doesn't represent correct reproduction, can you please elaborate or provide short video of the behavior ?

[math1man]

I reproduced the issue specifically in DartPad. Here's a video:

I also forgot to mention, but removing this one line fixes the issue:

Thanks for the update. I was also able to replicate this as reported.
