            Bug ID: 187084
           Summary: `change` event for input[type=file] does not fire when
                    different file with same name is selected
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Macintosh
                OS: macOS 10.13
            Status: NEW
          Severity: Normal
          Priority: P2

Steps to reproduce:
1. [input]select file1 on <input type="file"> 
  => change event is fired
2. [input]select file1 again
  => change event is NOT fired
3. Delete the file1, rename file2 to same name as file2
4. [input]select file2 (same file name as file1) 
  => change event is NOT fired

Expected:
Change event is fired every-time user select a file on prompt. Regardless of filename or even when same file is selected twice.
