Strange behaviours of formatting for double spans

[chengtie]

OS Version: macOS Sierra 10.12.2

VScode (which uses js-beautify as the underlying formatter) Version:

The shortcut shift+alt+f is used to format the whole document (without having to select anything), and cmd+k cmd+f is used to format the selection.

{ "key": "shift+alt+f",           "command": "editor.action.formatDocument",
                                     "when": "editorHasDocumentFormattingProvider && editorTextFocus && !editorReadonly" },
{ "key": "cmd+k cmd+f",           "command": "editor.action.formatSelection",
                                     "when": "editorHasDocumentFormattingProvider && editorHasSelection && editorTextFocus && !editorReadonly" },

My experiments show that formatting html does not work well for the following case:

<span>
    <span>try</span>
    <div>posted by</div>
</span>

will be formatted to

<span>
    <span>try</span>
<div>posted by</div>
</span>

Does anyone know what's happening?
