[MC-179171] When walking into the exact corner of a block, you go into crawling mode under the block

If you walk into the corner of a block very precisely, you will enter crawling mode under that block.

Environment

Windows 10, latest Java version, vanilla Minecraft dedicated server

This works as intended. See MC-96922

This is actually a duplicate of MC-177970. The reporter did not specify that they had an elytra.
