Waypoints disappear from locator bar even if they're still visible on the camera

The bug

If an entity has the waypoint_transmit_range attribute to a set range and the locator bar is enabled, the entity will display on it but will disappear when it’s on the edge of the camera, even though it is still visible for the player.

At the same time, the up and down arrows will display even though the entity is still visible on the camera.

How to reproduce

1. Summon a sniffer.

2. Execute the next command on the sniffer.

/attribute @n[type=minecraft:sniffer] minecraft:waypoint_transmit_range base set 60000000

1. Get near the sniffer and look around until the mob is halfway on the camera edge.

2. Notice the waypoint behavior on the locator bar.

Expected result

The waypoint would still be visible until the mob is completely outside the camera.

Observed result

The waypoint disappears even though the mob is still visible on the camera.
