Sitting in a minecart has slight downwards pitch offset [MARK INVALID]

Mark invalid: this seems to have been a visual mistake during resource pack testing

To Reproduce:
1.

/execute align xyz run tp @s ~ ~ ~ 

2. Look straight down and turn your head around to see that your cursor always aligns to the corner of the blocks

3. 

/execute align xyz run summon minecart

4. Sit down and look straight down and turn your head to see that your viewpoint is always slightly behind the corner, meaning your head tilts so far it goes behind you by a slight degree
