Execute is a little fishy

commands seem to share one condition boolean for all entities running at the same time instead of each their own.

ie: /execute as @e[type=arrow] at @s if block ~ ~ ~ minecraft:glass_pane run setblock ~ ~ ~ minecraft:air will only break the glass if all arrows are in glass pane blocks, if one arrow is in a glass pane and another is not, none of them will set air.
