Gtk DumpRenderTree can work correctly if there is not arguments in the function beginDragWithFiles.

(In reply to comment #0) > If there is not argument in function beginDragWithFiles, DumpRenderTree will crash. Why do we need to support such case? A test using beginDragWithFiles must specify arguments.

A test using beginDragWithFiles must specify arguments. In fast/files/file-list-test.html, if some files are selected, the onInputFileChange can be called, we can test the attribute length and items of FileList. In addition, we want to cover the scenario that no file is selected. If we use [] as the argument, if is fine. But for the robustness, I think it should support no argument, as GTK test shell does. https://bugs.webkit.org/show_bug.cgi?id=87696#c14

Do you think real browsers need to handle drag with empty file list? If not, beginDragWithFiles should reject empty file list and missing file list instead of accepting them.
