After Selecting A Date, Restoring Focus On Field Causes Year To Be 0000

[wisam22]

Love the library, very convenient solution to a common problem. However, I keep encountering the issue where after selecting a date, trying to reopen the date picker to change the date causes the year to break and always show as "0000".

Turns out this issue was specifically happening when I included a comma in my "format" parameter. I've decided to use a different format for the time being.
I was using: MMM DD, YYYY

Solve problem when we change a value of parseSplitDelimiter option of the plugin with ' - ' (Exactly Same Space Comma Space).
There is an issue with regex. When we try to set Mode as range & Format as MMM DD, YYYY (especially having comma) then split 2 dates string with 4 dates
Ex
Consider selected dates are Apr 1, 2017 - May 19, 2017.
when try to reopen calendar then split string with a regex /,\s*|\s+-\s+/ (that is parseSplitDelimiter option) then we get array
[ "Apr 1" , "2017" , "May 19" , "2017" ]

there are 4 dates, generate because of the wrong regex.
like,
[
Sat Apr 01 0 12:00:00 GMT+0530 (IST),
Fri Jan 20 17 12:00:00 GMT+0530 (IST),
Fri May 19 0 12:00:00 GMT+0530 (IST),
Fri Jan 20 17 12:00:00 GMT+0530 (IST)
]

that's why shows Apr & May month with 0000 years.
When we change parseSplitDelimiter option with ' - '
String split with correct two dates.
[ "Apr 1, 2017" , "May 19, 2017" ]
then generate only two correct dates.
like,
[
Sat Apr 01 2017 12:00:00 GMT+0530 (IST),
Fri May 19 2017 12:00:00 GMT+0530 (IST)
]

This is a temporary solution, need to find correct regex.
