WebUI: Test if links are opened in new tab correctly
    
    Test for PF#7137: [RFE]: Able to browse different links
    from IPA web gui in new tabs
    
    Test verifies whether opening target link in new tab
    navigates to target (desired behaviour) compared to creation of copy of
    current state of page on new tab (old behaviour).
    
    WebUI: Add method for opening link in a new tab
    
    Add `navigate_to_row_record_in_new_tab`  method.
    `navigate_to_row_record_in_new_tab` works as
    `navigate_to_row_record` but opens link in new tab instead and focuses
    on it.
