Date tag: problem selecting months

[ral104]

Users have reported an issue where they try to select a month of less than 31 days from a month of 31 days. Example: selecting February from the dropdown month list when the last tag placed was for 31st January. In this case, the month then 'slips' onto March. Seems to be because the tag is trying to find the 31st day of the new month, but can't, so moves onto the next month.

Easy for users to fix by simply changing the month again, but the problem is that they often don't notice the issue until they've finished the page.

This appears to affect all browsers.

@eatyourgreens any thoughts on whether this issue is fixable?

It's built-in behaviour in their browser: if you set a date to an invalid value, eg. '31 Nov 1917' then the browser corrects to the next valid date, '1 Dec 1917'.

if values are greater than their logical range (e.g. 13 is provided as the month value or 70 for the minute value), the adjacent value will be adjusted. from https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date

I've added some code to reset the date to the first of the month if the new month doesn't match the selected month.
