Wiki does not display Scalable Vector Graphics

[Jonathan Ferguson]

I have a wiki page with two images: https://wiki.ubuntu.com/JonathanFerguson/EthernetInterconnections

There are two images attached per: https://wiki.ubuntu.com/JonathanFerguson/EthernetInterconnections?action=AttachFile
Ethernets.svg
L2TPv3.svg

I discovered that when appending the URL with a query string, that the images display: https://wiki.ubuntu.com/JonathanFerguson/EthernetInterconnections?highlight=bogus

When looking at the source of the two pages, by puting the below strings into a browser:
 view-source:https://wiki.ubuntu.com/JonathanFerguson/EthernetInterconnections
 view-source:https://wiki.ubuntu.com/JonathanFerguson/EthernetInterconnections?highlight=bogus

Compare line 162 of both pages, it can be seen that the file path is mangled for https://wiki.ubuntu.com/JonathanFerguson/EthernetInterconnections
The same occurs for the second image at line 263
