.select Event has abnormal behavior with gr.File

[marcoquin]

Describe the bug

First of all, thanks for the tremendous work on gradio !

I try using gradio.File with file_count="multiple",. I also use in my code a file.select event. When I delete a file, the event is triggered except when the deleted file is the last in the gradio.File box.

Reproduction

import gradio as gr

with gr.Blocks() as io:
    title = gr.Markdown("1")
    file = gr.File(
        label="Upload Files",
        file_count="multiple",
        )

    file.select(
        fn=(lambda file: print("Event triggered!")),
        inputs=[file],
        outputs=[],
    )

io.launch()

I use the command uvicorn run:app (my python file is called run.py) I made a simple event that prints a message in the console, so you need to check the logs to see if the event is triggered or not.

Screenshot

Here is the precision of the precise file that does not trigger the select event (it is always the last)
