This is because signs placed on the ground are actually taller than one block.

Relates to MC-28561
Affects 19w35a and 19w36a. Can I request ownership of this ticket so I can update it as I test it alongside MC-28561?
Duplicate of MC-28561.
Signs have 12 pixels from top to bottom. However, there are another 4 block pixels above and below the sign, which total to 20, rather than the 16 that would be expected. Also, the sign is 24 pixels wide, rather than the expected 16.
This (alongside several other sign issues such as MC-2836, MC-28561, MC-157547 and MC-195472) could be fixed by using block models for signs rather than entity rendering, and adjusting the proportions for the signs.
Does MC-28561 describe your issue?

Is that a sign on top of a sign, MC-28561?
