Hopefully I can lay this out right.
I have multiple tabs open in my SeaMonky browser window. Several are various wp.com sites including their Support forum, Reader, and other sites I have there. One tab is my self-hosted .org install Dashboard.
On the self-hosted site tab, the dark grey topbar shows as usual, but the "Likes" notification star just lit up as it does on wp.com Dashboards. I am NOT logged in as the same User on the .org tab that I am on the others. It does not do that when I have the Dashboard open in another browser.
I'm just not sure if this is due to Jetpack or the browser somehow.
It's not a problem, I'm just curious.
