The bug
Blocks cannot be placed on fences with the off-hand.
How to reproduce
Hold torch in offhand
Right click on top of a fence
You can't place it
Code analysis
The method net.minecraft.block.BlockFence.onBlockActivated(World worldIn, BlockPos pos, IBlockState state, EntityPlayer playerIn, EnumHand hand, EnumFacing facing, float hitX, float hitY, float hitZ) returns true if your mainhand is empty or holding a lead. This is also the reason for MC-21433. Since the method returns true when there's nothing in your mainhand, the offhand is ignored.

Likely caused by fences having a right click action (for leashes).

It affects all blocks.

When you hold SHIFT you are able to place the block, however for the mainhand this is not the case, see MC-93651

Same reason as for MC-93651
The client thinks it interacted with its mainhand with the fence, and because of this does not try to use the offhand.

Looks like it is fixed in 16w39c probably because MC-93651 was fixed

Fixed in 18w20c, you can shift right click and place blocks on the fence.

Not fixed, that's the way it's always been.
