Month picker in combination with minDate/maxDate has inconsistent UI

[NicoHof]

Describe the bug

• If minDate is f.e. 20. May. 2023 I cannot select "May" in month picker mode
• This could be fine if the UI would show May as disabled state in this moment. Then it would be arguable to say May is not selectable since minDate is in the "middle of the month and therefore not available"
• But the entry is not in "disabled state" - User can click it but not "select" it.
• IMO this behaviour is strange and missleading for the user. If its not selectable (Button click) it should also be disabled for clicking, right?
• Preferred solution: May can be selected. In this example since minDate is 20. May. 2023, so May 2023 should be selectable as its inside of the "min date limitation"?

Expected behavior

• Can select May in this case as a month
• If not wanted by design: disable May for the user in the UI (disabled state)
