If I insert a SVGZ-image in the text/html editor in Enonic it renders correctly in the admin-panel. When I click on the ‘Preview’-button to open the page in a new tab the SVGZ-image is not displayed.
FYI Enonic XP by default sets headers to enable webserver compression when possible, so regular svg files will magically be compressed for most clients out-of-the-box
