Installation: "Search Engine Visibility" not keeping checked on error

[screamingdev]

Given your installing WordPress
and you reach the screen about site title, admin login and "Search Engine Visibility".

When you enable the checkbox for/near "Search Engine Visibility"
And fill nothing out for mail address
And press continue

Then an error message appears
And most fields are still filled out as before

---

Problem:

The "Search Engine Visibility" is no longer checked.
IMHO this should also stay as intended to.
