<input type="file" accept="image/jpeg" multiple>

The automatic conversion of multiple HEIC files to JPEG is slow on older machines. I would like to display a loader. I can already show a loader when the user clicks the input, and hide it when the "change" event fires. However the "change" event doesn't fire when canceling the "Choose files" dialog.

A solution could be an extra event that fires immediately after files are chosen (before conversion), or alternatively, an event for the Cancel action.
