The behaviour of minyear / maxyear attributes on the calendar field seems to no longer reflect the documentation, or that of how Joomla 3.10.x functioned.

Steps to reproduce the issue

Create a calendar field with minyear and maxyear attributes set to -10 and 1 respectively.

Expected result

Calendar year is clamped between 2013 and 2023

Actual result

Calendar year is clamped between the years -0010 and 0001

System information (as much as possible)

Joomla 4.3.0

Additional comments

https://docs.joomla.org/Calendar_form_field_type states "minyear (optional): set a signed integer for a number of years (-10, -2, 0, 7, 12, ...) to define the relative lower limit for the year selection. The user cannot select a year before this limit (starting with 3.7.0). If zero, which is the default, there is no limit."

It looks like this may have been of result of this commit (though I don't quite understand the motive behind said change)
