Wood placed inside a 1X1 hole burns way faster when placed vertically than when placed horizontally.

Steps to reproduce:

• Make an axe.
• Cut a tree and gather the wood.
• Make a flint and steel.
• Dig a 1X1 hole in the ground and place the wood horizontally.
• Light the wood using the flint and steel.
• Redo step 4 and 5 but this time place the wood vertically.

Result of the issue:

• The horizontally placed wood burns faster.

Expected behavior:

• It should take the same time to burn horizontally placed wood tha vertically placed wood.

Things to note:

• The issue occurs only when the wood is placed on a 1X1 hole and the exposed part is lit.
• The issue occurs with all wood types.
• The issue was done on SMP.
