The bug
When you click on the statistics section in the pause menu in single player mode, the game advances by one tick.
To reproduce
Ensure you are playing a singleplayer world which is not opened to LAN.
Run this command:
/setblock ~ ~ ~ repeating_command_block{auto:1b,Command:'tellraw @p {"block":"~ ~ ~","nbt":"LastExecution"}'}Press escape to pause the game.

Confirmed for 1.8.1 (MC-75472)
It doesn't seem to be always 1 tick though. It unpauses the game until the stat or achievement menu is done loading. It takes from 0 to 2 tick for me. (Tested with /time command)
This issue still exists in Minecraft snapshot 24w07a. Note that the issue is easier to reproduce when increasing the tick rate.
Confirmed in 13w38a/b/c, 13w39a, 1.16.1, 25w15a/16a. Not confirmed in 1.6.4 or older. This bug is also caused by achievements button, but not caused by advancements button.
Yay it's confirmed 😃
