Currently, when a filter is created for a layer's field (e.g. "name" field) the keys that are generated for the filter and displayed in the data browser are sorted alphabetically and not naturally. This makes e.g. number 70 to appear after number 100.

I think it would be more intuitive to sort the keys naturally and it would also be consistent with the behavior of layer's elements which are sorted naturally. I've attached a screenshot to illustrate the issue.
