Bug 40074 [navigation] Selection reset to previous item when arrowing in outline
build I20030710 - open a Java editor on a class with several methods - in the outline, select the first method - use the arrow key to go down one item - as soon as the delay passes and the new text range is selected, use the arrow key to go down another item - after the delay, the selection is reset back to the previous item
