Text input formats seem to have padding issues

[cdr0y]

Describe the bug
Input format behaviours are acing differenly between some modes. For example with a :formats={ input: 'dd/MM/yy' } i can type the date as 20/03/26 and it will auto focus that date on the datepicker, but if i type 20/3/26 it doesn't auto select. If i then add a space after the 'yy' in the date format it allows me to type the date as 20/03/26 or 20/3/26 and it will select and prepend the 0 itself. This is manageable, apart from i haven't been able to find a format to sayisfy this when i set the picker to range mode.

To Reproduce
Steps to reproduce the behavior:

1. ensure datepicker has a format, i am using 'dd/MM/yy' in this case
2. ensure datepicker has auto-apply (im not sure if this is required to replicate)
3. select a date in datepicker, then click the input to type
4. remove both month numbers and type 03 for march, it should select.
5. change month number to 4 for example, it will not auto select without the 0.
6. add a space to the format so it says 'dd/MM/yy '
7. repeat step 4 and 5, it will now autoselect the month as required.

This then happens with range but i cannot find a way to satisfy the format

Expected behavior
Date should auto select on the picker with the format passed in with or without the space at the end

Screenshots
no space no autoselect

space added, date autoselects and prepends the 0 if needed

apologies, this isn't the most straight forward issue to explain so if any further info is required please let me know and i will try and explain anything in more detail. This is fine on single date mode with the space as a work around, but not being able to type either format on range mode is killing me 😬

'dd/MM/yy '

I have no idea why this works, I guess it is something related to date-fns.

For your case, you actually want to use textInput.format property too

And pass :text-input="{ format: ['dd/MM/yy', 'dd/M/yy'] }"

However, there seems to be an issue in parsing logic, where the year value switches from e.g. 2025 to 0025
