Unancered web entry starts but no automatic cursor at login field

Remote Desktop manager can display a web entry with either 'External', 'Embedded' or 'Undocked'.
When we use any webpage that as a login field, most browsers are able to automatically display the text cursor on the login field.
If we use RDM, this function works with the External and Embedded option for display BUT not the Undocked option.

Ideally, I need the 'Undocked' option to do the same thing as the other onces.
I am forced to insert 'TAB' key for the login Macro and sometimes, this doesn't work.
I have no issues with my Macro when the text cursor is already present in the login field.
