I derived the following backtrace (by backtrace(), *not* a crash) from 
DocumentImpl::setFocusNode within dict.leo.org when the input element focus 
node is about being overwritten by 0. It shows that ensureNodeVisible is not 
involved:

The khtml: [void DOM ... ] newFocusNode: lines were temporarily inserted by 
me.
