click tracked quest list can show QuestLogFrame
but in combat is bad

because HideUIPanel/ShowUIPanel Protected during combat(by Patch 8.2.0 / API changes )

so,can fix it?
like :
function S_ShowUIPanel(frame, force)
if ( frame and (InCombatLockdown() or issecure() )) then
frame:Show();
else
ShowUIPanel(frame, force);
end
end
