Job inspector page icons broken when using reverse proxy

[rain]

Hello.

I am using Splunk configured as a reverse proxy.
The root_endpoint in web.conf is set to /splunk.
Most of the pages work fine, and most of the functions work fine as well.
However, in the case of the job inspector page, the path of the icon is broken and it is not displayed.

Are there any other options that need to be set?
