This PR ensures that the instructor "Problem Responses" report in Open edX includes all student responses to all problems under any selected block, including those that are nested or randomized (such as those from legacy library_content blocks). Previously, the report could miss responses to problems that were not directly visible to the instructor or admin user generating the report, especially in courses using randomized content blocks or deep nesting.
In courses that use randomized content (e.g., legacy library_content blocks) or have deeply nested structures, the instructor dashboard’s problem response report was incomplete. It only included responses to problems visible in the block tree for the user generating the report (typically the admin or instructor). As a result, responses to problems served randomly to students, or problems nested in containers, were omitted from the CSV export. This led to inaccurate reporting and made it difficult for instructors to audit all student answers.
