[BUG-202688] PRIM_MEDIA_HOME_URL causes background requests on every prim edit

[sl-service-account]

Steps to Reproduce

Created a script with a prim media setter.

Actual Behavior

When setting the home url of a prim's media, the server receives a request every time the prim is manipulated/moved/edited, regardless of whether the current prim media is the same url or not, or even visible/active.

Expected Behavior

Requests to the server should happen only when the media is displayed on the prim and rendered.

Other information

A script for testing. After applying script, select/move/morph/etc in edit mode and see the request messages appear.

default
{
    state_entry()
    {
        llRequestURL();
    }

    http_request(key id, string method, string body)
    {
        if (method == URL_REQUEST_GRANTED)
        { 
            string url = body;
            llSetPrimMediaParams(0, [PRIM_MEDIA_HOME_URL, url]); 
        } else {
            llOwnerSay("Request made");
        }
    }
}
