Task Manager portlet: Workflow Step filter not retained and Step dropdown empties after opening a content item

Problem Statement

In the Task Manager / Workflow Tasks portlet ("Filtered Tasks"), when a user
selects a Workflow Scheme and a Step to filter the task list, then opens a piece
of content (edit task) and returns to the portlet, the Step filter is lost and the
Step dropdown is empty. The user must re-select the scheme and click Reset to
filter again — repeated for every content item in the same step.

Steps to Reproduce

1. Go to the Task Manager (Workflow Tasks) portlet.
2. Select a Workflow Scheme, then select a Step to filter the list.
3. Open one of the filtered tasks / pieces of content.
4. Return to the Task Manager portlet.

Acceptance Criteria

The Scheme and Step filters remain selected and applied; the Step dropdown stays
populated with the steps of the selected scheme.

Start in the Task Manager / Workflow Tasks portlet and reproduce the filter behavior described: select a Scheme and Step, open a filtered task, and return. Trace how the Scheme and Step selections and the Step dropdown are restored; done means both filters remain applied and the dropdown stays populated with steps from the selected scheme.
