Stereo audio channels don't work how they should without directional audio

Since 1.13 there is a bug, where you cannot hear sound of the game in some channels if you are turned only one way (left or right) to the source. You can hear the sound only at one side and it is very irritating and unnatural. I'm not some audio expert, but I think, that if you had only one ear and you turn the way that your only ear is on one side of the head, with the source being on the other side of the head, you would hear it.

In past versions of Minecraft (in 1.12 and below) the sound system worked pretty good and it was great.

The following image visually shows the channels (1.8 in the left, 1.16 in the right):
