^ isn't this wrapping causing the bug with URLs on the SSL page in RTL? I was
thinking we should delete it

[meacer, 2014/10/02 19:42:48]

I'm going to do that in a separate CL. It's not clear to me yet whether SB or
SSL version is the correct one given the other RTL mark visibility bug.

[mattm, 2014/10/14 08:39:19]

Seems like it would be better to fix that first and then do the merge. Otherwise
you might regress whichever one is doing it correctly currently.

[meacer, 2014/10/20 22:43:15]

This part is blocked on https://codereview.chromium.org/643963004/ Once that's
fixed, I'll get back to this.

[meacer, 2014/11/19 21:29:59]

Done, since crrev/643963004 is closed.

[mmenke, 2014/11/10 16:42:58]

"LoadTime" is overloaded (See, for example, LoadTimingInfo), and "Data" is a
pretty empty term.  I would not have guessed it meant "static strings for this
specific SecurityInteristitialPage subclass".  Suggest LoadTimeData->Strings or
InterstitialStrings or PageSpecificStrings or somesuch.

[meacer, 2014/11/19 21:29:59]

Done.
