Brave shield breaks Cloudflare's Mirage function on mobile

Description of the issue:

I’ve noticed that on mobile, Brave blocks cloudflare requests linked to Mirage (https://developers.cloudflare.com/speed/optimization/images/mirage/) and therefore prevents certain elements such as images from loading. This problem does not recur on PC.

Exact URL of the website in question:

Blocked url: https://ajax.cloudflare.com/cdn-cgi/scripts/04b3eb47/cloudflare-static/mirage2.min.js

Did the issue present with default Shields settings? (yes/no)
Yes

Does the site function as expected when Shields are turned off?
Yes

Is there a specific Shields configuration that causes the site to break? If so, tell us that configuration. (yes/no):
No

Does the site work as expected when using Chrome?
Yes

Brave version (check About Brave):
1.78.102

Would a proper sample website url where this is hosted to confirm, I don’t see us blocking mirage any default shields

Have you tried this on mobile?

If I set “Allow all trackers and ads” then mirage is no longer blocked and the site logo is displayed.

See attached screenshots

On PC (no blocking) :

On mobile :

Brave shield (default setting)
If I put “allow all trackers and ads” in the shield, then it works correctly (whereas mirage is not a tracker).

Any custom list or rules? here’s mine.

After checking, “French Adguard” is activated in the list of filters and seems to be at the root of the problem.

Is there any way I can contact them to report the problem? (https://github.com/AdguardTeam/AdguardFilters/issues I think)

EDIT: They fixed the filter, thank you very much.

Correct, just report upstream to the list regional authors;

If its broken outside of regional, just check that first. I can also ping specific list authors if need be
