Start by locating the core file of the Uniform plugin, likely `jquery.uniform.js`. Identify the function that creates the styled wrapper or replacement element for form inputs. Currently, when a class like 'right' is added to the original button, it is not transferred to the generated element. Modify the code to copy all classes from the original input to the wrapper. Check if any existing tests cover class inheritance, and write a simple test to confirm the fix.
