unexpected ads notification shown when changing application focus

[btlechowski]

Steps to Reproduce

1. Clean profile
2. Enable rewards and ads
3. Open new tab and load https://hotel-deals.club/
4. Focus Brave
5. Wait 30 seconds
6. Focus another application

Optional:
7. Wait 30 seconds
8. Focus Brave

Actual result:

IMPORTANT: those notifications can exceed the max number of ads per hour
IMPORTANT: those notifications are always triggered thus the system can be gamed.

Focus change: Brave->Other App
this one doesn't look good, because the ad notification will be shown when Other App is in focus. Looks like Other App's notification.

Focus change: Other App->Brave

Expected result:

Only show ads notification when Brave is in focus.
Do not exceed the max number of ads per hour

Reproduces how often:

always

After further investigation it seems that the issue only reproduces when iab.com is opened in one of the tabs. The behavior seems intentional. Closing as invalid.

I'm receiving these on sites I have not allowed notifications for.

@archlemon the ad notifications are not related to the active tab. They are triggered by a background mechanism and they can only be globally disabled/enabled. Any site settings to disable html5 notifications still apply as normal.
