If window width is narrower than 995px,It fails without making reload.

Probably some kind of cairo overflow? The page is very tall, 91200px on my machine.

The link you provided is no longer available, can you please provide another one so I can test this on my end?
Also, is this still reproducible on your end ? If yes, can you please retest this using latest FF release and latest Nightly build (https://nightly.mozilla.org/) and report back the results ? When doing this, please use a new clean Firefox profile, maybe even safe mode, to eliminate custom settings as a possible cause (https://goo.gl/PNe90E).

Thanks.
