Navigated to the URLs provided in the issue on Chrome and Firefox.
Observing horizontally rendered tooltip in both the browsers.

@google@gtalbot -- Could you please re-check and provide us the update.
Thanks in Advance.

msrchandra,

Tooltip in both tests should be displayed vertically in any/all writing-mode-capable web softwares (Firefox 46+, Chrome 50+, Edge 12+, Safari 9+, Prince 10+, AntennaHouse 6+, etc.). Firefox already has a bug report on this; I merely wanted to state this. 

I am sorry: I do not understand what kind of feedback you are exactly expecting from me.

> Observing horizontally rendered tooltip in both the browsers.
This is - indeed - the actual result (or wrong behavior) of both browsers in both tests.

Thank you for providing more feedback. Adding requester "msrchandra@chromium.org" to the cc list and removing "Needs-Feedback" label.

Okay! I see the confusion now.

> What went wrong?
> The rendered tooltip should be displayed horizontally.

I meant to edit:

The rendered tooltip *_is_* displayed horizontally.

Able to reproduce this issue on Windows 10, Ubuntu 14.04 and Mac 10.12.3 with chrome #59.0.3048.0 and also in earlier version M48-48.0.2560.0, Since this is a non-regression issue marking it as untriaged.

Attaching the screen-cast for reference 

Note: For below M48 versions, for the provided url's, the Chinese text is displayed in the horizontal line, from M48 it has started to display Chinese text in vertical line.

Thank You...
