I've managed to reproduce this issue and I found out that it is not a bug in horizon. It is caused by the web server X-Frame-Options[1] header setting. Apache sets this as deny by default and the horizon page tries to access the router page from inside a <svg> tag (that is the network topology drawing). This <svg> tag counts as an <embed> tag with respect to the X-Frame-Options setting and thus the browser blocks the request to delete the router. I was able to fix this issue by changing the header setting in the apache configuration like this:
Header set X-Frame-Options: "sameorigin" This allows the page to be opened inside an <svg> tag as long as it belongs to the same web application (same origin) but would still reject it in case someone is trying to embed it in an external web site.
