If an entity with high velocity (for example, falling from 100 blocks) falls through tripwires that are hovering in air (no blocks underneath) the tripwire will not get triggered.

This needs some major changes.
I was trying to take time on items falling - Bug? - MC-116866
I am unable to reproduce this issue in 20w49a.
I can still reproduce this in 20w51a.
Affects 1.19-rc2 if you use small mobs such as silverfish.
Can Confirm in 1.19.3 Release Candidate 3, not fully reproduceable with large mobs. Fish, Silverfish, Endermite fail to trigger if Y Velocity is very high.
Can confirm in 1.19.4 on horizontal axis (gliding through cobwebs with elytra without being slowed down)
Can confirm in 1.20-rc1.
Confirmed in 1.20.4.
In 1.20.6.
Not completely fixed in 24w33a.
For example, for end portals:
create a default superflat world,
/setblock 100 -57 100 end_portal
/setblock 100 100 100 oak_slab
/tp @s 100 100.5 100
Then break the slab to fall
→You will still go through the end portal without being teleported.

This is also the case with entities moving quickly (such as fireworks).
