The month are shifting its position while selecting dates

[niloy369]

Hi,

I'm using the 3 dates inline view. I'm facing an issue that when I select a date from the 2nd or 3rd month the month comes at the first position. Is there any way to fix the position changing behavior?

i have created a quick and dirty patch. Don't know if this is the best solution and works with every option but for me it is working quite good.
