Redirection after email validation fails with relative URL

Thanks for your contribution! I left some feedback in the MR, please commit any future changes there.

Why did you revert the change? str_starts_with is still there.

I thought instead direct making changes, it's better to create patch file. So reverted it. Now, I have pushed that change also. Please review.

Just a note: symfony/polyfill-php83 is pulled in by Drupal core, and it provides str_starts_with() if the PHP version is less than 8.3.

I checked and you're right, symfony/polyfill-php80 including the str_starts_with function was added in Drupal 9.0.0 → . That would mean we need to drop support for Drupal 8, but I'm okay with that. Feel free to add back str_starts_with and drop support for D8 if you like.
