E-mail Notification Icon

When I get a new e-mail from my gmail account, and I open the message directly from the notification panel, the notification icon persists. I have to press 'back' to go back to my inbox after reading the message for the icon to go away. I can't just press 'home' - the icon will remain if I do that. Or I can clear the notification manually with the 'clear' button, of course. I assume this is not a glitch - this is the case with everyone's? Do you find this annoying at all?

I don't have the same problem with my corporate e-mail account, since the notification takes me to my inbox, instead of the message itself. The icon goes away as soon as the inbox is opened up.

Thoughts?

Noticed this, not a big deal to me. Not having voice BTooth function is a bigger deal.
