Line numbering out of sync for Windows users

[Jason A. Donenfeld]

I noticed this issue a while back too, and made this test case:

test case: http://data.zx2c4.com/italics-broken.html
broken case: http://data.zx2c4.com/italics-broken.png

I submitted it upstream to the Chromium project, and as of the current
version, it appears to be fixed in my browser.

Can you use this test case to file bugs upstream for your browsers?
