According to blink bug https://codereview.chromium.org/20049007, right now you webkit can eventually perform a O(n^2) scan through the document when moving the cursor up when at
the beginning of a document, which is pretty bad not only when in design mode or in editable elements, but also when you have enabled the caret browsing mode (EFL & GTK ports).
