My code calls promtLogin() on a button click.
Problem: When I login with my admin account, on my site, I come back on the current page, and In a text-input, the email-address of my other test-gmail-account is filled in, which I really didn't do in code. Even more, I only set the text-input once in my code somewhere else, with an empty string.
I already tried to change the text-input-element-id to something more specific, but still it didn't solve the problem. Before, the text-input-element-id was "input". Maybe this could be a reason of the bug, behind the scenes?
When I do the same by logging in my test-gmail-account, it is not filled in, so that approach works normal.
