Audio WebGL Audio Click Issue

I'm wondering if anyone has any insight into why this audio file would have a harsh scratch/pop sound at the end. This only affects the WebGL build, not Desktop. It occurs in multiple versions of Unity, though I created a build in Unity 2019.3.1f1 to demonstrate. The audio file, if you check the waveform, begins and ends with silence (0db) so it's not that. Also, if I either shave off a small amount of the waveform's end or add a small amount of silence to the end, the click goes away. Since I can't isolate the *why* I'm paranoid that the clicking might be browser dependent and I'll have no way of knowing. Any insight is appreciated!

Edit: I also tested to see if there is some minimum length for audio clips, but an even shorter version of this same sound had no clicking issue.

Test build is here: https://sparrowhousegames.itch.io/dgmmmf57pcbua8
Press space bar to fire the sound - extremely basic setup with a single audio source + clip.
Audio file (44100 Hz, Mono) download is also available for download on that page.

 

Just experienced the same issue - adding silence to the end of the track fixed the issue for me as well. Very strange...
