Video demo of the issue: https://drive.google.com/file/d/1EWN68J5njVkYiIOAqd9G78s9vRq5XCc1/view?usp=sharing

1. Sign in with email
2. Enter Reown OTP
3. The popup to sign the message does not pop up.
4. After refreshing, it does pop up.

Summary

I've noticed that when setting up SIWX with the Solana Adapter, that the email signup fails to bring up the popup to sign the login message. A user would have to refresh the page in order to get the popup, which seems highly impractical.

I could not reproduce this with Oauth or wallet logins. This only happens with Email login.

Expected Behaviour:
The popup would come up right after the OTP verification is successful, instead of requiring a manual refresh (as it works for Oauth login and wallet logins).

Note: I've tested in multiple Browsers, including one with no Browser Extensions.

Something similar happens on the official demo page:
https://lab.reown.com/appkit/?name=siwx-default

When using email sign in on the Solana Button, the Sign Message modal comes up but closes itself within 1-2 seconds. Refreshing the page, then opens it properly and allows the user to sign the message.
