My application has a modal requesting the user to input some text data into an editable text field for an object. The default value of that editable text area is set to the object's current value in the database. When the user submits the form, it saves the value of the editable text field in the database. However, when the user returns to the form a second time, the text displayed in the editable text field has been automatically capitalized and stripped of any punctuation or special characters. Is this the default expected behavior or editable text fields? I do not remember setting the field to do this.
