crash can occur when clicking on the rewards icon (particularly if BAP popup is displayed)

Description

Found while testing https://github.com/brave/brave-core/pull/7698

Sometimes tapping on the rewards icon in the URL bar crashes the browser. I’ve only encountered it so far when the BAP popup is overlapping the rewards panel (https://github.com/brave/brave-browser/issues/14108).

Steps to Reproduce

1. Clean profile, region = Japan, staging environment
2. Opened NTP
3. Opened Rewards panel, dismissed onboarding modal
4. Claimed UGP grant
5. Completed captcha
6. Waited a few seconds (for grant to process), then closed “It’s your lucky day” overlay.
7. Clicked elsewhere so Brave was not in focus
8. Then the BAP popup displayed overlapping the rewards panel
9. Click on the rewards icon in the URL bar

Actual result:

Brave crashes, crash report ID: 42120000-f138-da05-0000-000000000000

Expected result:

No crash, I believe without the BAP popup clicking on that icon would close the rewards panel

As per https://github.com/brave/internal/issues/747#issuecomment-761233483, the tooltip won’t be appearing as we’re basically ~2 days before March 13th hits. As per the specification, the tooltip stops appearing a week before March 13th. So a lot of the above cases aren’t valid anymore re: using the tooltip.
