Homepage dashboard pagelets are minimized after upgrading to PeopleTools 8.59

We configured multiple Homepage dashboards using PeopleTools 8.56 which are working fine in our production environment. However after upgrading to PeopleTools 8.59 all the delivered and non-delivered pagelets showing as minimized in the upgraded environment. Users have to manually click refresh icon on each pagelet to view the charts and other content. However if I configure a new dashboard with same delivered pagelets within 8.59 they display properly.

Trace logs show difference between native 8.59 dashboard pagelets vs upgraded 8.56 pagelets.

Native 8.59 PeopleTools trace has:  &parentSection(&scrollRowNum).PTNUI_MENU_DV.PTNUI_MENU_GRP.AriaAttributes = "role='menuitem' aria-expanded='true' " | &strAriaLabelSection;

Where as the upgraded 8.56 dashboards do not have aria-expanded='true' in its trace.
