Target selector parameter distance is useless for fishing_bobber

Neither the following two commands work:

/execute as @e[type=fishing_bobber,distance=..1] run say hi

/execute at @e[type=fishing_bobber] as @a[distance=..1] run say hi

 

The fishing_bobber cannot detect other entites or be detected by distance

The commands do nothing even if I swim at the same water block with the fishing_bobber.

If taking the distance parameter away, these commands work correctly.
