## **Manual testing steps**

1. Connect to the test-dapp
2. Enter this URL: 
```
https://metamask.github.io/test-dapp/request.html?method=eth_signTypedData_v4&params=[%22YOUR_ADDRESSS_HERE%22,{%22types%22:{%22EIP712Domain%22:[{%22name%22:%22name%22,%22type%22:%22string%22}],%22Mail%22:[{%22name%22:%22from%22,%22type%22:%22string%22}]},%22primaryType%22:%22Mail%22,%22domain%22:{%22name%22:%22foo%22},%22message%22:{%from%22:%22foo%22}}]
```
(replace `YOUR_ADDRESS_HERE` with a connected address)
3. Previous it would fail. On this branch it should correctly prompt a
signature confirmation.
