loadEnv overrides mode env file

[agileago]

Describe the bug

in this case. when i have a .env file

VITE_APP_BASE_ROUTE=/
VITE_APP_BASE_URL=$VITE_APP_BASE_ROUTE

and when i build for some mode . i will add .env.mode like .env.production

VITE_APP_BASE_ROUTE=/app/

i should get the result like this:

{
   VITE_APP_BASE_ROUTE: "/app/",
   VITE_APP_BASE_URL: "/app/"
}

but vite give the result:

{
   VITE_APP_BASE_ROUTE: "/app/",
   VITE_APP_BASE_URL: "/"
}

i think it is a error result. when i use the vue-cli . its result is right and nature
