Chromium tabs – can't update tab icon

Chromium tabs – can't update tab icon

I'm trying out chromium-tabs. I have an issue where the icon of a tab
never gets properly updated after it gets created for the first time. In
my CTTabContents subclass, I have:
- (void)tabDidBecomeSelected {
NSLog(@"selected");
[self setIcon:[NSImage imageNamed:@"default"]];
}
- (void)tabDidResignSelected {
NSLog(@"resign selected");
[self setIcon:[NSImage imageNamed:@"notification"]];
}
This should change the icon if the tab resigns its selected status to a
different one. But it doesn't. The icon never changes. Note that I've
tried the same exact calls in (id)initWithBaseTabContents:(CTTabContents
*)baseContents andJid:(NSString *)jid andStatus:(NSString *)status where
they work fine, so the calls fail only on an update of the icon later.
I've also made sure the functions are getting called (I see the log
statements). What's the problem here? Also, is this the fork that Chrome
actually uses? It obviously works in Chrome, which is strange... Am I
doing something wrong?
I even tried doing [[[self.browser.windowController window] contentView]
setNeedsDisplay:YES]; in the tabDidBecomeSelected functions, to force the
whole window to redraw, in case their code for updating the icon fails,
but still no luck.
