I took a look into this and I found that this is currently not intended behavior. I also found that this is a Canvas wide issue and our engineers are currently looking into this issue. I will go ahead and attach this case to the engineering ticket so when we find a resolution for this, you will be notified.
I apologize for the inconvenience this has caused. I appreciate your continued patience while our engineers work diligently. Feel free to reply back with any questions or concerns.
