Invalid HTML on card: SecurityError: Failed to execute 'insertRule' on 'CSSStyleSheet': Cannot access StyleSheet to insertRule

Hei there!

I downloaded the Incremental Reading add-on (v4103). I was trying to follow the instructions under the usage in the README file. I added a link but when I open up the deck I end up with the below error message.

I could reproduce this by

1. Copy https://en.wikipedia.org/wiki/Incremental_reading
2. Then paste it in after Alt+3.
3. Open the deck

I am running Anki:

Version 2.1.36 (53a984ba)
Python 3.8.0 Qt 5.14.2 PyQt 5.14.2

On macOS v10.15.7 (19H2).

Thanks.

I think you can fix this issue by commenting out the javascript in the width.js file

// if (screen.width > {maxWidth}) {{
//     var styleSheet = document.styleSheets[0];
//     styleSheet.insertRule(
//         "div {{ width: {maxWidth}px; margin: 20px auto }}", 0
//     );
// }}
