The protection for canvas fingerprinting seems not to be enabled.

Description

The protection for canvas fingerprinting seems not to be enabled.

Steps to Reproduce

When visiting https://browserleaks.com/canvas with the extension on/off, the Signature the web site provides is the same.

I.e, canvas fingerprinting does not seem to work.

Expected behavior:
The signatures are different.

Actual behavior:
The signatures are the same.

Versions

• Extension: 2024.10.16
• Browser: Chrome
• OS: Mac

Additional Information

The process of the fingerprinting on this page is explained here: https://browserleaks.com/canvas#how-does-it-work

And I checked the following things:

• if ddg's modifyPixelData() is called when the page calls toDataURL() on canvas: It wasn't called.
• if browserleaks.com is added to unprotected sites: No.

I found a commit which seems to have disabled canvas fingerprint protection.
https://github.com/duckduckgo/duckduckgo-privacy-extension/blame/main/shared/data/bundled/extension-config.json#L5084

If possible, could you please tell the reason why protection has been disabled for both audio and canvas?
I'm interested in the reason as a duckduckgo user :)
