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.

Typo on reproduce instruction: 
3. Delete the file1, rename file2 to same name as *file1*

Mass move bugs into the DOM component.

I am able to reproduce this bug in Safari 15.6 on macOS 12.5 and when selecting same file again, there is no "change event", it is only fired when I select another file. It is matching with Chrome Canary 106 but differs from Firefox Nightly 105, which fires change event every time I select file even if it is same file. Just wanted to share updated results. Thanks!

Also I think, this might be same as 227799 but just going to update this. Thanks!

https://bugs.webkit.org/show_bug.cgi?id=227799 is related, and is a nicer way of handling (2), where the same file and filename are selected.

I think we should still fire a change event for (4) though, when the name is changed.
