Merging branch keeps branch icon on the title tab for the file?

apologies if this was already asked/answered, but when I merge a branch, the branch logo remains in the tab title for the file. is this accurate? this seems exceptionally misleading if so. I have closed out the file and reopened and it appears to go away. very tedious process if this is what i need to do to get the visual reconfirmation that the branch has successfully been merged. (NOTE: i do check the reopened file and it has all of my updates) -Thanks.
