Datepicker Autoresponder

[bundfeg]

Hi,
I have an issue and wonder if you can reproduce it. I tested on firefox and chrome on macos and windows.

When I select the autoresponder start-date as the last day of any month, I cannot select anything in the future for the end-date.
The top right arrow is animated and seems to be clickable but it is not. As soon as I change the start-date to anything before the last day, everythings fine.

Thanks for looking into it,
Chris
