Why doesn't openPage work with an array of pages (Vue CLI, WebPack4)?

Question

webpack

I set up devServer and for some reason openPage does not work correctly with an array. What am I doing wrong? According to the docs, string/array strings are supported. Webpack 4.46.0.

openPage: '/app.html' //открывает localhost:8080/app.html (ок)
openPage: ['/app.html'] //открывает localhost:8080 (а должен app.html)
openPage: ['/app.html', '/second.html'] //открывает только localhost:8080 (а должен app.html и second.html)

I tried checking the config with

vue inspect --mode development > webpack.config.js

but for some reason there is no devServer section.

Congratulations, you've found a bug in @vue/cli. Get them an issue on github.
