Wav file without extension immediately snaps back to starting position on drag end or click

[Artforge]

Bug description

Using two files, identical aside from the addition of .wav to the filename, the one without the file extension exhibits unexpected behavior when attempting to drag to a point in the timeline, immediately returning to the original starting position

Environment

• Browser: Chrome
• OS: Mac

Expected result

After dragging to any point in the waveform, it should stay at that point, awaiting further action

Obtained result

After dragging to any point in the waveform, it immediately snaps back to the start once the mouse is released

Screenshots

Problem behavior (original file, proper mime-type, but lacking file extension)

failing_example.mov

Expected behavior (.wav added to the file name)

working_example.mov

Make sure your server sends the right MIME type in the Content-type header for files w/o an extension. Otherwise the browser may not be able to guess the correct type and thus fail to play it. Closing as "won't-fix".
