[veb] C compilation error

[Jengro777]

Describe the bug

pub struct App {
	veb.Middleware[Context]
        veb.Controller  // error
	veb.StaticHandler  //error
}

When using type aliases in App structures,

 veb.Controller
 veb.StaticHandler

A C error occurred

Reproduction Steps

structs/structs.v

module structs

import veb

pub struct Context {
	veb.Context
}

pub struct App {
	veb.Middleware[Context]
        veb.Controller  // error
	veb.StaticHandler  //error
}

main.v

import veb
import structs

type AliasApp = structs.App
type AliasContext = structs.Context

fn (mut app AliasApp) index(mut ctx AliasContext) veb.Result {
	return ctx.json('success')
}

fn main() {
	port := 9008
	mut app := &AliasApp{}
	veb.run[AliasApp, AliasContext](mut app, port)
}

v run main.v

Expected Behavior

No errors or a friendly "v" error prompt

Current Behavior

Jengro@Jengro-PC:~/Documents/Dev/v-product/vprod-workspase/example/app$ v run main.v
================== C compilation error (from tcc): ==============
cc: /tmp/v_1000/main.01K41RR17CZCAF0GXNJVH7HSHC.tmp.c:19546: error: field not found: controllers
=================================================================
(You can pass `-cg`, or `-show-c-output` as well, to print all the C error messages).
builder error:
==================
C error found. It should never happen, when compiling pure V code.

A simpler example

import veb

pub struct Context {
	veb.Context
}

pub struct App {
	veb.Middleware[Context]
	veb.Controller
	veb.StaticHandler
}

type AliasApp = App
type AliasContext = Context

fn main() {
	port := 9008
	mut app := &AliasApp{}
	veb.run[AliasApp, AliasContext](mut app, port)
}
