HTML 5 Users Getting Around Private Message Setting

A colleague and I were recently testing out the new HTML 5 client for Adobe Connect, and we noticed that participants using the HTML 5 client could use the private message feature, even though we have it disabled on our Adobe Connect account (setting: "When Chat pod is active, disable private messages").

Users on the desktop client cannot send private chat messages (as intended), but HTML 5 users were able to send private chat messages to anyone.

Is Adobe aware of this glitch? If so, when will it be fixed? Because of it, we will keep the HTML 5 client disabled for the time being.

Thanks for your help!

P.S., if it helps, we're using Adobe Connect 10.5.1
