Year selection not showing up on second click in IE 11

[El-Devoper]

The first time you click on the year the list is shown. If you click a second time or on a second dialog i.e. a from and until date selection, the list visually disappears. You can still click and a year is selected but it's a shot in the dark. The polyfills "CustomEvent" and "scrollIntoViewIfNeeded" are included. No console error is thrown.

had the same issue, I fixed this by adding years.classList.remove('zoomOut'); at mdDateTimePicker.js:864
``
...
if (mdDateTimePicker.dialog.view) {
viewHolder.classList.add('zoomOut');
years.classList.remove('mddtp-picker__years--invisible');
years.classList.remove('zoomOut');
years.classList.add('zoomIn');
// scroll into the view
currentYear.scrollIntoViewIfNeeded && currentYear.scrollIntoViewIfNeeded();
} else {
...
