White line around extension pop-up

As shown in Figure 1, open any extension program with a pop-up window. Move the mouse over the pop-up window, and a white line will appear on the left and bottom of the pop-up window. I have tested the Chrome browser and did not encounter this issue, as shown in Figure 2.

OS：Windows 11
version of Opera One：128.0.5806.0

I can confirm.

Example extension:

manifest.json:

{
    "manifest_version": 3,
    "name": "Extension Popup White Border Test",
    "version": "0.1",
    "action": {
        "default_popup": "popup.html"
    }
}

popup.html:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title>White Border on Extension Popup</title>
        <style>
            * {
                background-color: black;
                color: white;
            }
            body {
                width: 300px;
                height: 500px;
            }
        </style>
    </head>
    <body>
        <p>There shouldn't be a white border for this popup.</p>
    </body>
</html>

It's in current Opera Stable, Opera GX and Opera Developer. I know the border used to not be there, but I'm not sure if the change is intentional or not.

@Opera-QA-Team, Do you know if the white border is intentional?

@andrew84 Do you remember if anyone else has complained about this on the forums?

Don't know.
Btw, I can't confirm the issue here on win 10.

I can see here that the Extensions popup is cut here on the right and the thing I mentioned earlier regarding the odd shadow effect for the toolbar popups.

@andrew84, We also encountered popup issue in Firefox and we implemented a fix for Firefox only using CSS and on other browsers works fine.
