 * dash-style to camelCase conversion
 * A custom data attribute name is transformed to a key for the DOMStringMap entry by the following:
 *
 * 1. Lowercase all ASCII capital letters (A to Z);
 * 2. Remove the prefix data- (including the dash);
 * 3. For any dash (U+002D) followed by an ASCII lowercase letter a to z, remove the dash and uppercase the letter;
 * 4. Other characters (including other dashes) are left unchanged.
