Cannot see discussion

**Bug: PR Discussion tab renders blank on direct URL access

URL:** upstage/dp-bench · feat: Sync evaluation pipeline with latest repo (NID filter, Hungarian matching, merged tables)**

Steps to reproduce:

1. Directly access the PR discussion URL (or hard refresh)
2. Discussion tab is completely blank

Expected: discussion content visible Actual: blank white space below the tab bar

Additional info:

• API endpoint returns full data normally: GET /api/datasets/upstage/dp-bench/discussions/2 → 정상 응답
• When navigating via SPA routing from another HF page, commits briefly flash then disappear
• Reproducible consistently**
