Closing as working as expected as two different tabs were opened. One from rewards and another when you manually typed the url. Thanks

@tmancey I have opened only one new tab. I have enabled rewards from BR panel but I haven't clicked on rewards settings to open the rewards tab. I have just clicked on + new tab icon and which triggered two new tab events with diff ids. The issue was reproducible only for Windows. I will provide the recorded file shortly.

@tmancey Please find the recorded file, I can reproduce the issue consistently in windows, after enabling rewards, I am not clicking on Rewards setting in the BR panel hence there is no tab which has brave://rewards page. After enabling rewards I am just clicking on + icon, a new tab is opened but two events are triggered in the log:
Opened a new tab with id 5 and Opened a new tab with id 7 which is wrong as I have opened only one new tab.

@GeetaSarvadnya This is working as expected as on the video I only see the 2nd "Opened a new tab with id" appear when you open the About page.
