Mail.yahoo.com - anti-adblock that can only be dismissed after a countdown

Description of the issue: When logged in to Yahoo! Mail https://mail.yahoo.com/, it will show an anti-adblock prompt at the upper right side part of the page every few minutes. The prompt will take focus and will not allow you to interact with the rest of the page. It can only be dismissed after a countdown (probably to frustrate the user into disabling their ad blocker).

Exact URL of the website in question:
https://mail.yahoo.com/ (must be logged in)

Screenshot of the ad as it appears in Brave:

Did the issue present with default Shields settings? (yes/no) Yes. (Standard Trackers & Ad Blocking)

Does the site function as expected when Shields are turned off? No, because ads won’t be blocked when Shields are turned off. (Expected: Ads are blocked.)

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? No. The anti-adblock also appears in Chrome with uBlock Origin, even with uBlock filters, EasyList, EasyPrivacy, AdGuard and Fanboy’s Annoyances Lists enabled.

Brave version (check About Brave):
Version 1.17.73 Chromium: 87.0.4280.67 (Official Build) (64-bit)

Submited a fix incoming. (Just enable Ads/Tracker = Aggressive mail.yahoo.com)

Give it 24-48hrs for this to be rolled out.

Any update on this, guys??

In shileds, switch to Aggressive in Ads/trackers. I just re-tested this, seems good.
