Summary

Allow the promptText property in TextArea, TextField, and PasswordField to contain any character.

Problem

Previously, the promptText property had restrictions in some cases which limited the values it could take and modify its value by removing newlines "\n". Also binding the property when it has line breaks this would throw an exception which was handled in the TextInputControl control but this imposed unnecessary constraints.

Solution

Allow the promptText property to take any value. This provides more flexibility when using TextArea, TextField, and PasswordField controls. A promptText value that contains newlines will continue to appear in a single line in the single-line controls TextField and PasswordField and as a multi-line in TextArea.

Specification

The change is behavioral: previously, there were unspecified restrictions on the promptText value in certain cases. Now, these restrictions have been removed, and the property can accept any value.
