Component: InputMask – AutoClear moves value to front

[DaSchTour]

Describe the bug

When inputing a value in the middle of an inputmask the value is shifted to the beginning.
In the example I have a something like a data mask mm/dd/yyyy and input only mm/09/yyyy on blur this becomes 09/dd/yyyy

Environment

Nothing special, just using inputmask with autoclear set to off

@mertsincan I would like to fix this issue, but currently unit testing is completely broken so I have no idea how contribution is possible at the moment. That's really frustrating. I would have fixed this issue weeks ago if I would now how to contribute.

To add to this problem, if the pattern has a fixed value somewhere in it, the fixed value will be inserted and moved up front too.

i.e., given the pattern "9999999-001" with [autoClear]="false", on focus the input will show _______-001. On blur, the input will show 001____-001. If you focus->blur again: 001001_-001 and so on.
