<!-- Describe the feature you'd like. -->
When using `editor.emmet.action.balanceOut` or `editor.action.selectToBracket` starting at the end bracket or HTML tag, the selection direction should be start to finish.  That will allow you to use Shift + Up and Shift + Down to expand the selection.  For example, below demonstrates what happens when you select from the ending brace and then try Shift + Up.
