Avoid to reset input file with Next.js and Server actions

[federicocappellotto97]

Hello, i'm setupping a form using server action, but my problem is the input file is resetting also if validation is not successful

Here's an example Code Sandbox

As you can see if you upload an image, and then you send the form with an invalid email the input file is resetted, instead the email input is not.
How can i avoid this? Thanks!
