Field tabbing is not working as expected in Mendix 7.4.

After upgrading Mendix version from 6.9 to latest version 7.4, we observed that "Tab" key on keyboard is not taking user to next field.
  
  Our analysis - Assume that we have a Dataview (DW1), ListView (LW1) and Dataview(DW2) configured on a page in sequence with one field in each view. If we place cursor on the field inside dataview (DW1) and press on tab, cursor is moving to field which is in DW2 instead of LW1. 
  Dataview have a Tab index setting on it but not list view. Could it be the reason for this issue?
    
    Is this a known issue to Mendix?
