unclear what is focused on Tip banner when not enough BAT - follow up to 6147

[LaurenWags]

Description

Found while testing #6147

If you do not have enough BAT for the preselected button on the Tip banner, there is no visual indication that the Tip banner is in focus (no buttons show an outline on the banner to indicate focus). However, if you have enough BAT for the pre-selected button, you can see the outline on the Send Tip button indicating that it is in focus on the banner.

Steps to Reproduce

1. Clean profile on staging, using version 1.1.4
2. Enable rewards, claim grant.
3. Visit laurenwags.github.io and open tip banner
4. See that the Send Tip button has outline.
5. Close tip banner
6. Navigate to kjozwiakstaging.github.io and open tip banner.

Note - if you do this with the monthly tip banner instead of one time tip banner, you will encounter #6914

Actual result:

Nothing appears to be in focus. My guess is that the focus is actually on the Send Tip button but it is hidden behind the not enough funds notification banner.

Expected result:

Something should be focused as the Send Tip button is below.

Can we close this since we have a new tip banner? @LaurenWags

[LaurenWags]

@karenkliu let me revisit this one. I think so, but I'd like to double check.

Issue still exists, however tip banner design has changed significantly. Closing this issue in favor of #14595.
