This is still a problem in 3.6.
Bringing up a browser. Squeak hangs, eventually crashes because it's out
of memory.
Preferences for inboard scrollbars and hidden scrollbars are set.
The problem is that the scrollbar keeps getting alternately hidden and
shown, and there's a possible recursion:
PluggableTextMorph>>extent:
PluggableTextMorph>>resetExtent
PluggableTextMorph(ScrollPane)>>hideScrollBar
PluggableTextMorph(ScrollPane)>>hideOrShowScrollBar
PluggableTextMorph(ScrollPane)>>setScrollDeltas
