Issue with UIFC list

The up/down arrow keys are behaving incorrectly in UIFC. The list is not redrawing properly.

Example script:

"use strict"
load("sbbsdefs.js");
load("uifcdefs.js");

uifc.init();

var ctx = new uifc.list.CTX();

var menuTitles = [];
menuTitles.push("test1");
menuTitles.push("test2");
menuTitles.push("test3");
menuTitles.push("test4");
menuTitles.push("-----");

var selection = uifc.list(WIN_SAV, "Testing", menuTitles, ctx);
uifc.bail();
writeln("selected " + selection);
