Magic Trackpad scrolling in Visual Studio Code Supervisor AddOn does not scroll the document contents

**Device model, version and app version**

Model Name: MacBook Pro (15-inch, 2019)
macOS Version: 12.0.1 (21A559)
App Version: 2021.11.1 (2021.266)
Safari Version: 15.1 (17612.2.9.1.20)

**Home Assistant Core Version**
core-2021.11.5

**Describe the bug**
In the "Studio Code Server" AddOn, when using the gestures (2-finger swipe up/down on magic trackpad) it does not scroll the contents of the document being edited. Instead, it scrolls the entire AddOn window (including for example the explorer view of files etc). Scrolling works properly in Home Assistant in Safari.

**To Reproduce**
Install Studio Code Server AddOn. Open a long file (eg. the homeassistant.log) and try to scroll using the trackpad. I suspect this also occurs when using the Magic Mouse. Same issue with the MacBook built-in trackpad.

**Expected behavior**
Contents of document being edited should scroll, not the Studio Code Server's entire window.
