Does something like the below (untested in the extreme) help?
Hi Peter,

This has been tested extensively by the ChromeOS team and said that it does
appear to fix the problem.

Could you get this into mainline, and tag it for stable so that it can be
backported to the appropriate stable releases?

Thanks for the fix!

Hi Peter,

I just don't want you to forget about this :-)
