GIA-3210 - Added font size data attribute to content page body node for all relevant templates that contained the FONT_SIZE static string, having the attribute hard coded in the template reduces JS load at compilation time. Also added split() method to the window.fontResize function so that the replacement string passed into the function splits the string object inorder to set the attributes value to the integer only.
GIA-3210 - Remove JavaScript debugging console output window
