XML export different since update

The Share dropdown at the bottom of the calendar that exports an XML file is exporting a file that appears to be in the XML format, but is a .vcs file (xCal vs. vCal or iCal)

Please explain why this has changed and if it is possible to export the previous file format.

Example of the file that currently downloads:
BEGIN:VCALENDAR

VERSION:2.0

PRODID:-//146.148.80.135//NONSGML kigkonsult.se iCalcreator 2.24.2//

CALSCALE:GREGORIAN

METHOD:PUBLISH

X-FROM-URL:[removed for security]

X-WR-TIMEZONE:America/New_York

BEGIN:VTIMEZONE

TZID:America/New_York

X-LIC-LOCATION:America/New_York

BEGIN:STANDARD

DTSTART:20181104T020000

TZOFFSETFROM:-0400

TZOFFSETTO:-0500

RDATE:20191103T020000

TZNAME:EST

This is not XML.
Example of what it used to look like:
<?xml version=”1.0″ encoding=”utf-8″?>

<iCalendar xmlns:xCal=”urn:ietf:params:xml:ns:xcal”>

<vcalendar>

<version>2.0</version>

<prodid>-//Pentabarf//Schedule 1.0//EN</prodid>

<x-wr-caldesc>FOSDEM 2016</x-wr-caldesc>

<x-wr-calname>Schedule for events at FOSDEM 2016</x-wr-calname>
