How do I enable smart HTML tag indenting in Sublime Text 3?

I don't remember exactly when this functionality stopped working, but I always had Sublime Text do auto indenting properly. For example, if I type `<div>` and then press Enter, the caret would automatically make a tab on the next line. Similarly, when I closed tags, they would automatically un-indent by one tab (such as when pressing alt+. in order to close a tag). This functionality seems to have disappeared, at least in ST3, and I can't find any way to get it back. Anyone have any ideas? Edit: it might be useful to add that PHP auto-indenting works just fine, such as making indentation between brackets.
