Unhandled error presented when making a Commit while the file is still being uploaded in the platform.

Hi there,

I'd like to raise this issue on Github when I upload files through the platform.

When I go to "Add file" drop-down menu > Upload files" and upload a file, I see the progress bar showing the file is being uploaded, however the tool gives the option to "Commit change" while the file is still being uploaded, which takes me to a possible unhandled page error showing:
"error page (HTTP ERROR 400): This page isn't working at the momentIf the problem continues, contact the site owner."

When this issue happens, I also need to return to the previous page and upload the file again.

I imagine that is not very common for people do this in the platform but I'd like to suggest that the "Commit changes" button get disabled while the upload is still occurring, and enable only after the upload is complete to avoid this issue.

Thanks
