oneOf{const,title} with boolean type properties causes titles to be displayed in lower case

[mfulton26]

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.

Description

Bug

Steps to Reproduce

1. Define a schema with a boolean type property
2. Define an enum using the alternative oneOf{const,title} for that boolean type
3. Use some uppercase letters in the enum/oneOf titles
4. Render the form and note how the uppercase letters have been converted to lowercase. 😢

Here is a shared playground link demonstrating the issue.

Expected behavior

Mixed case radio/select options

Actual behavior

Lowercase only radio/select options
