[Sub Agents] The summarized report from subagents is blocked by the 'ask user' prompt

see screenshot below:

when the response says: `Research is complete and synthesized below; I’m checking whether you want any follow-up comparison detail.`, it then calls 'Ask User' to asking for review and choose the next action, however at that point the synthesized report is not output at all until I have to choose "Nothing to do", then it started outputing the report below that.
