Gradio `File` component doesn't display uploading progress bar

Describe the bug

Gradio File component doesn't display progress bar in some cases. Gradio is making 2 requests to it's backend, when gr.File upload is started - one POST to the /upload endpont and one GET to the /upload_progress endpoint.

So, POST /upload endpont calls track method of FileUploadProgress instance and populating self._statuses dict of FileUploadProgress instance with upload_id of the file, and GET /upload_progress endpont basically returns stream of events of file with upload_id (uploading progress of this file).

OK.

But:

If GET to /upload_progress is executed FIRST (before the POST to the /upload), then this GET request will fail with FileUploadProgressNotTrackedError error, because there is no such upload_id in self._statuses dict of FileUploadProgress instance yet. And in this case, there will be no progress bar of uploading the file on frontend.

Reproduction

This bug is reproduced sometimes, but sometimes there is no bug, it depends on the order of execution of GET and POST requests mentioned above. So, just try to ulpload different files several times:

import gradio as gr

with gr.Blocks() as demo:
    file_input = gr.File(
        label="test",
    )

demo.launch()
