Dero web wallet (wallet.dero.io) remembers my seedphrase when I recover my wallet using it.

[HACKER097]

When I recover my wallet using the seed and reload the page, I need to enter my password to open the wallet again. But If i click "Restore Wallet using SEED words (25 words)", My seedphrase is already entered in the "25 seed words" feild from the last time. It stays that way even if I delete my wallet or reload the page. The only way to make the field blank again is to close the tab and open the wallet in another tab. While I haven't tested, this might also be an issue with other recovery options.

I am using Waterfox Browser 78.14.
