Screenreader doesn't announce selected date when range is active

[JoseeWouters]

Describe the bug
We are using two date pickers to have the option to select a specific date range with a start date an end date. We have used several of the available Aria labels to make sure a screenreader announces correctly the selected date and also the focused date.
But if you have a date selected, for example september 1st to september 25th and after this you select september 15th, the screenreader will not announce this as selected.

To Reproduce
Steps to reproduce the behavior:

1. Make sure to have a screenreader active (I'm using NVDA)
2. In a date picker where you can select a date range
3. select a start date
4. select an end date
5. The screenreader will announce the selected dates correctly
6. After this selection, select a new date in this date range
7. the screenreader will not announce this new date

Expected behavior
I expect the screenreader to announce the newly selected date, always, regardless of other previous selections

On top of this, the screen reader does not announce the keyboard navigation of the dates, therefore, the users doesn't know what date is high-lighted by the keyboard navigation.
