Date mask with trailing dot (d0.M0.) can lead to doubled dots

[ischerf-buhl]

🐞 bug report

Is this a regression?

No (I think)

Description

When using the date specialties (d0 + M0) with the German format of dots after them, there is a problem if a user only enters 2s. The month then is considered February, but when you keep typing, there is not only one dot appearing, but two.

Expected: 22.2.
Actual: 22.2..

If you do this with a 3, it will only show as 3.3. and not let you continue to enter anything.

🔬 Minimal Reproduction

Stackblitz Example
Please enter a lot of '2's in the field.

🌍 Your Environment

In my local environment I have this with [email protected] + [email protected]
In stackblitz it is the same behaviour with [email protected] + [email protected]

Anything else relevant?

In my case, I can get around this issue by using leadZeroDateTime as you can see in the example.
