editurl with default value which requires login first.

I'm able to edit a record using an url like this:

When navigating towards such url when I'm not logged-in, zoho navigates me to a login page first and thereafter the record edit is accessible.

So far so good.

However, I want to edit a record an set a default value for some field, the url looks like this:

(I've tried the url like this too:

)

This works fine, and the default value for the field is set correctly.

The problem:

When not logged in into zoho and using the url with default values, after the login dialog, the default values for fields are ignored.
