I have reported this issue internally: CRI 84100157. Will update here once I get any information.

I got information below:
We have accepted the issue and filed an internal bug for tracking.
It is lower priority and no ETA right now. We will investigate and hopefully it is a quick style print-media fix, but this may be bug in the screenshot utility which would take more time.
Thanks for the information.
