slider.updateIcon doesnt update Bitmap icon

[AlexMercier]

About this issue

slider.updateIcon(identifier, ImageHolder(bitmap)) doesn't display icon given as Bitmap

I just updated my code and update library from v6 to new kotlin v 8.0.2
and I have method to download png images from web to bitmap and then set it on ui thread to slider items.
Firstly I have PrimaryDrawerItem without icon, then my code download bitmap and after checking that bitmap is loaded I try to set it to slider:

if(slider.getDrawerItem(id)!=null && b!=null) { //b is bitmap 
        slider.updateIcon(id, ImageHolder(b))
        MyLog.log("$id is set icon")
}

I can see in log next lines: (It means that identifier and bitmap is correct)

106 is set icon
103 is set icon
112 is set icon

but in fact my items have no icons.
For testing i tried to set icons from IdRes drawables and it work. But with bitmaps it seems them don't work.

first 2 items loaded by res id, next 3 items without icons is a set as bitmap icons...
