To get to the last used fragment in the evalation dialog, one has to press the down-button all the way through the list. The dialog should either open with the last used fragment or an empty textfield, and then allow to select older fragments with the up-button.
current:
[empty] <- inital selection
first used fragment
...
last used fragment
requested:
first used fragment
...
last used fragment <- inital selection here
[empty] <- or here
I thought this was already covered by
IDEA-28216 but it apparently just swapped the behavior of the navigation buttons. I should have been more precise there. Sorry :(
