Describe the bug

When using DatePickerRange with min_date_allowed and max_date_allowed, choosing a date for start date, there will be one more day after the max date displayed as available but not really selectable.

Expected behavior

Nothing should be available outside of the min_date_allowed and max_date_allowed range?

Here's the minimum code to reproduce it.

from datetime import date
from dash import Dash, dcc, html, Input, Output, callback

app = Dash(__name__)
app.layout = html.Div([
    dcc.DatePickerRange(
        id='my-date-picker-range',
        min_date_allowed=date(2024, 6, 1),
        max_date_allowed=date(2024, 6, 15),
        initial_visible_month=date(2024, 6, 1),
        end_date=date(2024, 6, 15),
        minimum_nights=0
    ),
    html.Div(id='output-container-date-picker-range')
])


@callback(
    Output('output-container-date-picker-range', 'children'),
    Input('my-date-picker-range', 'start_date'),
    Input('my-date-picker-range', 'end_date'))
def update_output(start_date, end_date):
    string_prefix = 'You have selected: '
    if start_date is not None:
        start_date_object = date.fromisoformat(start_date)
        start_date_string = start_date_object.strftime('%B %d, %Y')
        string_prefix = string_prefix + 'Start Date: ' + start_date_string + ' | '
    if end_date is not None:
        end_date_object = date.fromisoformat(end_date)
        end_date_string = end_date_object.strftime('%B %d, %Y')
        string_prefix = string_prefix + 'End Date: ' + end_date_string
    if len(string_prefix) == len('You have selected: '):
        return 'Select a date to see it displayed here'
    else:
        return string_prefix
