The popover of DatePicker or Timepicker is not fully displayed when used from inside ExpandableSection.

How do you reproduce the problem?

import { ExpandableSection, DatePicker, TimePicker } from '@patternfly/react-core';
export const ExpandableSectionBasic: React.FunctionComponent = () => {
  return (
    <ExpandableSection toggleText="Test" isExpanded>
      <DatePicker/>
      <TimePicker/>
    </ExpandableSection>
  );
};

Expected behavior
A clear and concise description of the expected behavior.

Is this issue blocking you?
Found a workaround by overloading --pf-v6-c-expandable-section__content--TranslateY property from css as follows:

.pf-v6-c-expandable-section {
  --pf-v6-c-expandable-section__content--TranslateY: 1 !important;
}

Screenshots
Following screenshot shows DatePicker's popover truncated:

Following screenshot shows TimePicker's popover menu truncated:

Jira Issue: PF-3935

Start by reproducing the issue with DatePicker and TimePicker inside an expanded ExpandableSection in PatternFly 6. Inspect the SCSS controlling the --pf-v6-c-expandable-section__content--TranslateY property and compare the behavior with PatternFly 5. Done means both popovers are fully visible without the reported CSS workaround.
