[Desktop] window size affects error message display in Rewards

[LaurenWags]

Description

Certain window sizes cause a problem displaying the "error" notification when trying to use Uphold rewards in a region without support (ex. NY). From what I've observed, in this case the error flashes on screen but doesn't persist. This then puts the user into a bad state because they haven't been given the error, so they have no information. If they click on "Verify Wallet" nothing happens on screen - basically it appears as though the integration is broken.

Note - in the terminal logs you do see this when clicking on Verify Wallet

[ REQUEST ]
> URL: https://api-sandbox.uphold.com/v0/me
> Method: UrlMethod::GET
[15114:775:0929/074839.490957:INFO:uphold_wallet.cc(89)] BAT not allowed

Steps to Reproduce

1. Clean profile, staging, enable Rewards. Note your window size.
2. Claim UGP grant.
3. Click on Verify Wallet.
4. Login with credentials for an NY account.
5. You will be redirected back to brave://rewards page

Actual result:

when window size is 1013px tall and 1200px wide (my default window size) the error message flashes and goes away quickly. Note how clicking on Verify Wallet doesn't do anything from brave://rewards and clicking on this from the panel opens a blank new tab. User is in a bad state at this point. (gif picks up at step 4 from above)

it's tough to see in the above gif, but here's a slightly different window size where you can see the flash of the error a bit better:

Expected result:

If I size the window down (to 699px tall by 928 px wide), no issues with error message displaying:
