It's possible to get slowed down by unreachable cobwebs

Steps to reproduce:

1. Create a superflat world.
2. /setblock 10 -51 10 stone
3. /setblock 5 -54 6 stone
4. /setblock 6 -54 5 stone
5. /setblock 5 -54 5 cobweb
6. /tp @s 9.701 -50 9.701 135 50
7. Press and hold sprint, jump and forward button at the same time.

Observed result:

You will be slowed down by the cobweb.

Expected result:

You won't be slowed down by the cobweb since it's blocked by the stone.

It could only be reproduced consistently on -X -Z axises. On +X +Z, it won't work. On +X -Z or -X +Z axises, it is inconsistent.
