In order to fix concerns from #241 (https://github.com/telerik/kendo-ui-core/issues/241) the Autocomplete now shows a full list of items when the text entered has been deleted. This ignores the MinLength option, and can cause unresponsiveness in the browser (since MinLength is generally there to reduce the amount of results). From #574 this new functionality is intentional (and as such, the thread was closed as won't fix), but in practical terms, this causes issues for a lot of people. If you really don't want to enforce MinLength when 0 results are returned, perhaps adding an extraoption like 'AlwaysEnforceMinLength' would solve this problem
Reproducible with suggest: true and serverFiltering: true
