Input component escaping Ampersand in Storybook

[mahalde]

Currently the form control input component escapes to HTML entities (> to >) only in display. The problem is that the ampersand part of the escaped HTML entity also gets translated to an HTML entity on the next keystroke. This leads to more and more text in the input field. The only way of clearing the input field is then to press CTRL + Backspace to clear everything in the input.

Steps to reproduce:

1. Visit the form control input component page.
2. Type an ampersand or > or < in the input field.
3. Press the backspace key.

Expected: The character should be removed.

Actual: The displayed string grows larger on every keystroke.
