Since Structure Blocks were pulled out from behind Experimental Gameplay, I've been wanting to use them for mapmaking.  According to the Official Minecraft Wiki, I should be able to load a vanilla generated structure 9i.e. a Village house, a Jungle Pyramid, etc.) using a Structure Block.  I cannot figure out how this actually works (or whether this works at all).

Steps to Reproduce:
1. In a Creative World, place a Structure Block, open the GUI, and set it to 'Load'
2. Attempt to try and type in a structure name using the <folder name>/<structure name> syntax from the wiki
3. For example, I should be able to type in "village/plains/houses/plains_medium_house_1"

Observed Results:
The GUI edits the Structure Name by a) adding the "namespace" mystructure: to the beginning, and b) truncating the name of the entered structure.

Note that the length of the name truncation is less characters than what would be needed to enter the structure <folder name>/<structure name> for most of the structures as they are listed on the wiki.

Expected Results:
The structure that I input should appear in the preview window of the GUI.

In the example above, I should get a plains_medium_house_1 to be able to drop into my creative world.

Also note that documentation and useful information on how Structure blocks work is woefully inadequate.  It does not help that Structure Blocks seem to work differently from Java to Bedrock, which is easy to work around in most cases by not one where the exact file path and structure name is needed.
