Simple answer is NO.
I can say this though, the first 8 slots do not get altered, in contrast to this, if you complete the "Maze" objective and gain 1 or 2 slots will be added to it, this applies to Treasure Pest objective. So, dependent on the total slots that you are available to hold items (i.e. 8, 9, 10, 11 or 12), will NOT re-adjust items in those slots.
Basically, anything above the maximum of 12 will re-adjust when using EES items.
EDIT: I chose #3... but I think maybe #2... basically, the only items that do NOT switch around is based on the how many items you can hold outside of EES items... example.. if you can hold 9 items out of 20, only the first 9 slots will NOT change the items that are stored there.
