Describe the bug

If I assign the attribute disabled="true" to a datePicker element with showIcon="true", the datePickerTrigger button is disabled via a style, but can still be focussed via keyboard and opened (the datepicker overlay will be displayed at the end of the document).

Reproducer

Reproduction (Tested with Version 14.0.12):

1. Set the datepicker button variant to disabled=true <p:datePicker id="button" value="#{calendarView.date7}" showIcon="true" showOnFocus="false" disabled="true" />
2. Use the keyboard to navigate to the disabled DatepickerButton
3. press Enter to open the overlay
4. Scroll to the bottom of the page, where the overlay is displayed:

Expected behavior

If I set the DatePicker to disabled, the tabindex on the datePickerTriggerButton should be set to -1.
