Wrong shortcut expansion in CSS if TAB key or suggestion list are used

[VIPStephan]

Describe the bug
If I type “cnt” and expand it using the TAB key or the entry in the code suggetion tooltip, it will produce content: '${0'}; – note the non-matching single quotes; the block will be highlighted until the second quote (the ending quote) and the curly bracket is excluded from the marker. I seem to remember that this used to work before; perhaps some update (either the plugin or Nova) broke it?

To Reproduce
Steps to reproduce the behavior:

1. Open a CSS file
2. Write a CSS rule, e. g. body:before {}
3. Type “cnt” on a new line inside the rule; the code suggestion popup will show an Emmet option as first item; hit the TAB key or click on that option
4. See error

Expected behavior
It should produce content: '${0}'; as output (i. e. correct nesting of quote/curly bracket).
By the way: this works correctly if Ctrl-E is used to expand the shortcut.
