When selecting the section titled "music & sounds" in "options", the "click" noise that is heard when selecting a button is heard twice. I'm assuming this happens because there is another button that takes the spot of this button as soon as you click on it (which is the volume controller for "blocks"), and the game may automatically register the click that was used for selecting the "music & sounds" button for the "blocks" slider. I tested this in many versions, and it is present in the latest snapshot as well as in 1.16.4 and in most, if not all, of the other versions before 1.16 until 1.8, where the bug is no longer present. 

Steps to Reproduce:

1. Enter Minecraft
2. Navigate to "Options"
3. Select the button titled "Music & Sounds..."
4. Observe how most times, the "click" noise is played twice

Observed Results:

The "click" noise that is played when selected a menu button in Minecraft is heard twice when selecting the button titled "music & sounds".

Expected Results:

The "click" noise should only play once, as it does for all of the other menu buttons, including "chat settings", which has a similar layout (there are sliders that appear in the next menu upon clicking this button), but does not play the sound twice.

Notes:

This bug does not affect gameplay but is a slight auditory bug in Minecraft's options section. Also, I believe that it only pertains to the "music & sounds" section and no other sections; notice how in the attached video, this section produces the bug, but the section titled "chat settings" does not produce the bug, and it has a similar layout.
