Cannot copy-paste date between 2 datepickers. Found issues:

• Cannot select whole date by mouse. Now it's reset to select only one date part by mouse. Current workaround: clicking Ctrl+A with keyboard.
• Similar: I think selecting whole date should be a default behavior when I click datepicker by mouse, because after keyboard navigation by TAB  the whole date is selected by default. No selection after clicking is also applicable (as it's done for standard input type="text").
  
• Similar: cannot select whole date by mouse with double click (expected behavior for inputs).
• Related issue: navigating by TAB across datepickers is too long. Because date parts are also "navigated". E.g. to navigate by TAB between 2 datepcikers I need to press TAB 4 times! If I have more datepickers, navigation is too annoying.
• Minor: cannot drag&drop dates between datepickers.

Can be reproduced in any Kendo example (and browser) on the documentation site.
