Gmail does not show certificate selection dialog when "exchange_login_certificate_alias" is not specified in managed configuration

Hi,

I am trying to configure Gmail to work with Exchange ActiveSync within a work profile via managed configuration according to the documentation - https://support.google.com/work/android/answer/7065453 

The following parameters are specified: "exchange_host", "email_address", "exchange_username", "exchange_authentication_type" (allow_modern_authentication)
The "exchange_login_certificate_alias" parameter is not set. I expect that the user will have to select a certificate via the system dialog.

But as a result of such a configuration, the certificate selection dialog is not displayed to the user. The mail setup process is interrupted and the error message "Try again later, or contact your IT admin" is displayed

However, if I specify any random value in the "exchange_login_certificate_alias" parameter, the certificate selection dialog is displayed.

I would like to know whether this is expected behavior or a known issue?
