Current Behavior:
When using a webmodule that rewrites the url like this:

luakit.add_signal("page-created", function(page)
    page:add_signal("send-request", function (_, uri)
        return "https://example.com"
    end)
end)

Other webmodules that depend on send-request will now fail, because nothing is triggered:

luakit.add_signal("page-created", function(page)
    print("'page-created' is triggered!")
    page:add_signal("send-request", function(_, uri)
        print("'send-request' is triggered!")
    end)
end)

This'll only print 'page-created' is triggered!:

Desired Behavior:
When redirecting/changing the destination URL, send-request should be triggered again (as the URL is changed).

How can we reproduce it (step by step):

1. Create 2 webmodules, wm_one.lua:

luakit.add_signal("page-created", function(page)
    page:add_signal("send-request", function (_, uri)
        return "https://example.com"
    end)
end)

and wm_two.lua:

luakit.add_signal("page-created", function(page)
    print("'page-created' is triggered!")
    page:add_signal("send-request", function(_, uri)
        print("'send-request' is triggered!")
    end)
end)

2. Now load both in your userconf.lua or whatever you use:

require_web_module("wm_one")
require_web_module("wm_two")

3. Open luakit (should redirect to https://example.com)

As you can see, only 'page-created' is triggered! appears in the terminal

Note about webkit issues:

If you're reporting a rendering issue, please test it with the gnome
browser ephiphany as well. If the issue occurs there too, we're very
likely not able to help. These issues should be reported to webkit:
