getting full file name from parsing FormData payloads

[jimmywarting]

Bug Description

Reproducible By

var fd = new FormData()
var f = new File(['abc'], 'folder/readme.md', { type: 'text/plain' })
fd.set('x', f)
new Response(fd).formData().then(fd => fd.get('x').name).then(console.log)

Expected Behavior

To log folder/readme.md

Logs & Screenshots

actual output: readme.md

Environment

• Darwin 22.4.0 arm64 arm
• NodeJS v20.2.0

Additional context

• All browser (including Deno & node-fetch) returns the full filename.
• constructing a File that includes / is totally fine. new File(parts, 'dumm/di/dumm.txt')

i guess why the hole reason why this is even supported is b/c browser have been able to use

<input type=file webkitdirectory>

then when you select some folder, and upload them all the content-disposition would then be:

Content-Disposition: form-data; name="files"; filename="folder/readme.md"

busboy have this preservePath option... would like for you to set it to true
