netlify deploy --build --prod runs with dev context

Describe the bug

Hello, i think that when i run deploy command with --prod context should be production ?
Or context depends on git branch, etc?

ps:
I know that i can pass --context

Steps to reproduce

1. create new branch ex: feature/netlify
2. run netlify deploy --build --prod

Configuration

[build]
command = "npm run export && cp ./netlify-headers/_dev-headers ./out/_headers"
publish = "out"

[[headers]]
for = "/*"
[headers.values]
X-XSS-Protection = "1; mode=block"
X-Content-Type-Options = "nosniff"
Referrer-Policy = "no-referrer-when-downgrade"
Content-Security-Policy = "default-src 'self' http: https: ws: wss: data: blob: 'unsafe-inline'; frame-ancestors 'self';"
Permissions-Policy = "interest-cohort=()"
Strict-Transport-Security = "max-age=31536000; includeSubDomains; preload"

[context.production]
command = "npm run export"

Start by reproducing netlify deploy --build --prod with the shown [context.production] configuration and compare the selected build context with --context. Use the deploy command's context-selection entry point and its existing tests, if present; done means --prod consistently selects the production command rather than the dev context.
