Additional Information

this is not the correct value. We shouldn't be changing css, but we have problem with keys

more info:

current master is working correctly (d6447e8), problem is only bat-integration branch. And that's because we changed the logic, how we are getting passphrase.

Master:

browser-laptop/app/browser/api/ledger.js

Line 1563 in d6447e8

passphrase: parsedData.properties.wallet.keychains.passphrase,

BAT: https://github.com/brave/browser-laptop/pull/11231/files#diff-3cdfdb124f718787d584e9e2b82fcedcR1554

Problem is that logic changed in bat library.

after talking with @mrose17 about it, this is new way of doing backup, so will fix css accordingly

[NejcZdovc]

fixed with #11231

[srirambv]

Added QA/checked as the workflow is changed to single key and this is obsolete

[luixxiul]

the single key should not overflow anyway.

[bsclifton]

Removed milestone because this screen was reworked- this is no longer valid

[luixxiul]

This line of #11291 actually prevents the overflow.

The hack with max-content which I have added will be removed with #11344 so no-qa-needed for this issue anyway.
