Issue number: resolves #28602
What is the current behavior?
We animate to the new date when the value is changed, but we do not account for multiple selection. This behavior is valuable for when the value is set asynchronously on a different month than what it shown.
However, this is confusing when there are multiple dates selected in different months, because we do not reasonably know which date to animate to.
What is the new behavior?
Datetime no longer animates to the new value if more than one date is selected, and the selected dates aren't all in the same month.
An alternative strategy would be to always animate unless one of the selected dates is in the month currently being viewed. However, this would still mean guessing at which value the user wants to see, which we are trying to avoid.
Based on this PR: #28605
Does this introduce a breaking change?
