Module Custom Component iFrame moving window bug

If I have 2 browser windows open with each window working on a different module:

Browser window #1: working on Module #1
Browser window #2: working on Module #2

both modules contain a custom component. If I open the iFrame code popup window in both modules, then I try to click and drag to move 1 of them, the iFrame in the other browser window will also move it's position. 2 for 1, but not necessarily the best kind.

EDIT:
I noticed if you have any popup code window open on both browser windows they will move at the same time whenever you try to move either one. I've tried with the Data Source, Model and IFrame code popup windows.

is this intentional and what the multiplayer beta feature thing is for?
