promptForFiles ignores the accept attribute

[goulvench]

I'm using Droppable to allow drag'n dropping files on regular file inputs, and I noticed that the accept attribute was ignored.
That's because the virtual input used in promptForFiles does not copy the accept value.

Since I'm using plain inputs, turning isClickable: false (instead of true, the default) allows the native filepicker to open, including its accept, which solves the issue for me in this case.

When the element is a regular file input, it would be more intuitive to copy the input's multiple and accept attributes to the virtual input used in promptForFiles, and only use the defaults otherwise.
