Analysis upload fails with `rejecting SARIF, as there are more threadflow steps per result than allowed (19350 > 10000)`

从 CodeQL Action 的上传步骤以及 upload-lib.js 和 analyze-action.js 中引用的堆栈帧入手；使用所示的 systemd 工作流和示例作业重现该故障。确定是否可以缓解 SARIF 的 threadflow 限制，然后记录一份可用的配置，或确认上传仍会被拒绝。

Hello!

Today I wanted to enhance our CodeQL scan in the systemd repo by using the security-extended and security-and-quality query sets, but after adding them the CodeQL action can no longer upload the resulting SARIF file:

Waiting for processing to finish
  Analysis upload status is pending.
  Analysis upload status is failed.
  Error: Code Scanning could not process the submitted SARIF file:
  rejecting SARIF, as there are more threadflow steps per result than allowed (19350 > 10000)

Since the build & analysis finishes successfully and only the last step fails, I don't think this is an issue on our side - is there something which can be done to mitigate this or we're out of luck?

Thank you!
