What happened?

Doesn't work even with a super basic HTML page. No console or javascript errors. Seems to be somewhat inconsistent as on a production page some drop downs work and some don't.

For the test HTML page source code see the first comment in this post.

Computer is running:
Windows 11 build 10.0.26100.4061
Edge 136.0.3240.92

Troubleshooting steps attempted:

  • Repairing Edge (this did not fix things)
  • Cleared site cookies/cache (did not fix things)
  • Incognito Window (did not fix things)

Current Work-Around:
Currently as a work-around we loading the impacted site using IE compatibility mode. Obviously this is not a good long term solution.

Importance

Apparently my pasted HTML got formatted. Here is the sample page we tested:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Select Example</title>
</head>
<body>
<h1>Select Your Favorite Fruits</h1>

<form>
<label for="fruits">Choose fruits:</label><br>
<select id="fruits" name="fruits">
<option value="apple">Apple</option>
<option value="banana">Banana</option>
<option value="orange">Orange</option>
<option value="grape">Grape</option>
<option value="mango">Mango</option>
</select>
<br><br>
<input type="submit" value="Submit">
</form>
<p>Hold down the Ctrl (Windows) or Command (Mac) button to select multiple options.</p>
</body>
</html>

Could possibly be a regression of #5148

Let me know if HAR logs are needed. I can submit them for the sample test page I provided, but unfortunately not for the internal app. We haven't received any other reports of this issue happening recently, but the one user has continued to use IE compatibility mode.
