This doesn't work for sort keys that are deeply nested, e.g. 0.8.9 should be sorted before 0.8.10

I tested that this works with localeCompare's numeric sort:
console.warn(['11', '10', '9', '33', '8', '30', '3'].sort((a, b) => b.localeCompare(a, 'en', { numeric: true })));
console.warn(['4.11', '4.10', '40.8', '4.9', '4.33',].sort((a, b) => b.localeCompare(a, 'en', { numeric: true })));
console.warn(['4.10.34', '4.10.3', '4.10.29'].sort((a, b) => b.localeCompare(a, 'en', { numeric: true })));There was a problem hiding this comment.
Oh, I didn't realize those weren't just numbers, which wasn't clear from the comment. 👍

Fixes #897 by correctly sorting coordinate paths prior to deletion.
We're using "coordinate paths" to store which vertices are selected. These paths are stringified indices into the coordinates array, and can be multiple levels deep separated by
.. When deleting vertices, we sort them in reverse order to make sure that we invalidate the indices by deleting vertices that come before another vertices scheduled for deletion. This works if we have fewer than 10 vertices. However, the alphabetical sort means that we'd delete note10before node9. This PR fixes this by using a numeric sort.
