Describe the bug

The default value for process.argv does not match between above mentioned versions, when run with the browsers mode.

• With 1.6.0 it's was undefined
• With 2.0.x it is an array with few values

If we use vite-plugin-node-polyfills to pollyfil the process it had different weird behavior.

• With 1.6.0 it's was []
• With 2.0.x it is undefined

The vite-plugin-node-polyfills version is same in both cases, so the shims does not change at all.
