robhogan@, could you please take a look as this is M51 Stable Blocker and we're cutting M51 Stable RC on Tuesday, May 31st. The fix has to be landed and merged to M51 by Tuesday 1:00 PM PST. Thank you.

I don't see this as a release blocker but maybe I'm biased. This is happening on a Japanese page format on an English-language page on a single platform.

THere's some weird confluence of conditions happening here that someone with a Windows build will need to look at.

Could you confirm that it is actually my CL? In other words, can you revert my CL and build without it? Does it happen in 52?

robhogan@ normally testers don't have resources to do bisecting/reverting with local builds. Developers need to find the actual CL caused the bug and assign to the actual owner.

I think it is expected because of the pagination styles in the page. The first page happens to be blank when the page is in certain sizes. The CL changed the behavior because the CL changed the printing scaling factor. I also reproduced the result on chrome m50 on Mac and Linux.
