The bug
Unlike the bug where you appear to be sitting much lower in a minecart, this offset is to the side. You can achieve this effect by placing a minecart on a curved/bent rail, and entering it.

Confirmed for 14w31a.
When you enter the Minecart on diagonal rails you appear shifted to the side. This continues on straight tracks and fixes itself when you derail.
Cannot reproduce on releases 1.14.4 or 1.15.2 or snapshot 20w06a. It appears to have been fixed by having the minecart's shadow snap to the center of the minecart itself right after it's placed. If a minecart is placed on a bent rail, you can actually see the shadow quickly snap itself to the minecart only moments after placing it. If a player gets on the minecart while the shadow is still snapping, they will follow the shadow as it snaps to the center, until it stops, properly centered. I have yet to test 1.14.3 or earlier, but the bug does ocurr on 1.13.1 as listed.
Is this still a concern in the current Minecraft version 14w19a / Launcher version 1.3.11 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
