I noticed the same bug but with a div-tag and a p-tag as a child - this seems to be reproducible with every html tag. My OS: Windows 7, Sublime Text V2. However, I had Ubuntu installed for a day and noticed that this bug doesn't exist when using the Linux version of Sublime Text 2.
The bug can be described as follows:
div [TAB] [ENTER] [CTRL+SHIFT+ENTER] lorem [TAB]
Thanks in advance for dealing with a bugfix.
btw: You don't have to delete the tag, just navigate to it once again and press tab.
