+Subject: [PATCH] http2: set drain on stream end
+
+Ensure that on_frame_recv() stream end will trigger a read if there is
+pending data. Without this it could happen that the pending data is
+never consumed.
+
+This combined with https://github.com/curl/curl/pull/10529 should fix
+https://github.com/curl/curl/issues/10525
+
+Ref: https://github.com/curl/curl/issues/10525
+Closes #10530
