oneOf/anyOf does not infer type or respect subschema-level type

Prerequisites

• I have read the documentation;
• In the case of a bug report, I understand that providing a SSCCE example is tremendously useful to the maintainers.
• Ideally, I'm providing a sample JSFiddle or a shared playground link demonstrating the issue.

Description

Explicitly giving the type in a root-level schema works fine.

However, the following do not render anything, though are supposed to still render a dropdown:

• Not providing the type at all (in which the type should be inferred to be a string)
• Explicitly providing the type only in subschemas

Version

@epicfaace saw this happening the other day, it looks like there is some code to detect but this is not working, I have a few examples of this on what I am currently working on which also requires #885 / my if then else stuff
