Thank you for creating Brave Browser! I’ve been using it for a few months.

When using the browser zoom on some pages I developed, I can’t calculate the zoom level via JavaScript.

Take a look at how JS gets the browser zoom here: https://github.com/jenswittmann/CurlyFramework/blob/9e845e44a6d7c8ac6c2ace732e78b5377cb67bec/index.html#L757-L788

There is also a demo to test in Brave and Chrome to see the problem: https://curlyframe.work/#zoomdetector

Steps to Reproduce

  1. Open https://curlyframe.work/#zoomdetector.
  2. Zoom in on the page using CTRL and +/-.

The problem is that you can see the calculated zoom level via JS in Chrome, but not in Brave.
