What problem does this new feature solve?

• Full context: https://www.notion.so/walletconnect/Web3Modal-Email-Broken-on-Brave-be2a045358194508bf727d276dd19814?pvs=4#ed67982e932b4a8fb5239af12b41768e
• Our target devices for playwright functional tests currently do not cover all browsers we want to ensure support for (e.g. Brave).

Describe the solution you'd like

• Expand the playwright pipeline to run against Brave (or emulate/approximate Brave's behaviour) and any other browser envs that are currently not covered
