478179 - Incorrect font-weight for italic Helvetica Neue

Status: RESOLVED DUPLICATE of bug 420981

(Core :: Graphics, defect)

Description

[philippe (part-time)]

Attachment: test case

given 
body {font: 300 1em/1.5 'Helvetica Neue', sans-serif; /*Helvetica neue light*/}
italicised text will use the ultra light face of Helvetica Neue, instead of the one with the same weight (in the example case: 'Helvetica neue light'.

In the testcase, italics for font-weight 100, 200 and 300 all use the ultralight face [1])

This is a duplicate of bug 420981.  The testcase is different the underlying Apple bug is the same.  Apple keeps telling me it's "fixed in SL xxx" but it still hasn't been corrected, even in the latest seed.  Basically Cocoa tells us that the Light and UltraLight faces have the same weight.  So if you want to mark something as blocking, mark it on bug 420981 please.

But this particular bug didn't happen until recently. Or did bug 455243 just make it visible ?

Before the 20090112 build (and 20090115 Shiretoko build), Helvetica Neue Light was used for both the normal font-style and the italic font-style. After that, UltraLight is used for font-style italic for for font-weight 100,200 and 300.

Yeah, that must be what's happening.  Vlad put in a sort and that's probably subtly reordering things such that the behavior changed.  I'll take a look.

Not marking blocking as per comment #1 -- sounds like we just permuted the behaviour.

Same problem as bug 420981, fixing there.
