There is a layout problem just under the navigation bar at http://www.ritterclan.org. It looks like an issue with table colspan support, partial reduction attached. Works correctly in IE and Opera. Firefox also has a problem, but a different one.

Created attachment 461607 [details] Safari 15.6 differs from other browsers I am able to reproduce this bug in Safari 15.6 on macOS 12.5 where few picture elements are missing as pointed in the screenshot. All other browsers (Chrome Canary 106 and Firefox Nightly 105) render them fine, although Chrome do show some "Plugin" missing icon on right side. Thanks!
