Hextech Bomb Disables Items For Entire Round

As the title states hextech bombs are disabling items for entire the entire round not the intended 8 seconds.

When a round starts and the bomb is thrown for 8 seconds the items are X'ed out as intended after the X's are removed items are still not working.

I've observed this over 4 games with multiple items such as ionic spark, bloodthirster, and static shiv.
