I am running into an issue with allowing copy/paste of dates into the filter and cell input fields. Currently, the date fields have validation to support MM/dd/yyyy, and users of the app may be trying to copy dates in that are MM/dd/yy. I would expect Kendo to auto format the date to MM/dd/yyyy after the paste happens, or at least allow support for that, but it doesn't seem to happen.

In the cell, when putting in MM/dd/yy, a validation message appears saying the date is invalid, and there doesn't appear to be a way to override that. In the filter, when putting in MM/dd/yy and submitting the filter, it doesn't stick and completely ignores the date put in.

Steps to reproduce (filter):

1. Copy a date formatted as MM/dd/yy
2. Paste it into a date column filter
3. Attempt to apply filter
4. Notice that the filter is ignored

Steps to reproduce (cell edit):

1. Copy a date formatted as MM/dd/yy
2. Paste it into a cell datepicker field
3. Notice the validation flags it as an invalid date
