Description Irakli Gozalishvili 2020-07-18 02:00:04 PDT 
According to the web File spec https://www.w3.org/TR/FileAPI/#file-constructor passed name should be normalized by replacing all `/` chars with `:` (quoting relevant fragment below)

> Let n be a new string of the same size as the fileName argument to the constructor. Copy every character from fileName to n, replacing any "/" character (U+002F SOLIDUS) with a ":" (U+003A COLON).

Safari does not seem to escape `/` characters. Running following code produces `foo/bar`


```
new File([], 'foo/bar').name // => "foo/bar"
```

While according to the spec it should produce `foo:bar`.


Firefox seems to behave according to specification:
Chrome seems to exhibit same bug https://bugs.chromium.org/p/chromium/issues/detail?id=1107071

Spec agreed that no special treatment need to be performed:

Commit - https://github.com/w3c/FileAPI/commit/a7f27059f04dfe81d2b58c516549fd7004cf5e29

*** Using below:

console.log(new File([], '/').name);

All browsers (Chrome Canary 106, Firefox Nightly 105 and Safari 15.6) generate "/" in console.

Since all browsers match and spec are changed, I am going to mark this as "RESOLVED WONTFIX". Thanks!
