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. 1846063 1 webkit-bug-importer 2022-02-25 09:56:34 -0800 <rdar://problem/89479482>
