The Bug:
Normally, when you interact with a button, the minecraft:ui.button.click sound is played to give the player an auditory indication that their interaction was successfully executed, however, this isn't the case when joining a realm through double-clicking on it.
The minecraft:ui.button.click sound is played when joining realms through clicking on the "Play" button, therefore also introducing an inconsistency.
Steps to Reproduce:
Navigate to the realms menu.
Join any realm by double-clicking on it and listen closely as you do this.
Take note as to whether or not the minecraft:ui.button.click sound is played when joining realms through double-clicking on them.
Observed Behavior:
No sound is played.
Expected Behavior:
The minecraft:ui.button.click sound would be played.
