Fields in Email Alerts as well as on Case Records are displayed with CSS parameters

Email Alerts and fields on Case records are displayed with CSS parameters. When user opens some existing Case or save a new Case it can happen that the text is changed into strange text with characters - CSS parameters as well as delivered via Email Alert.

Following text can appear e.g. in:

1. Message on Case record
2. In Email Alert sent based on change of Case record

message text#next_pages_container { width: 5px; hight: 5px; position: absolute; top: -100px; left: -100px; z-index: 2147483647 !important; } 
#next_pages_container { width: 5px; hight: 5px; position: absolute; top: -100px; left: -100px; z-index: 2147483647 !important; }

1. The incorrect text on the Record can be based on how user entered the value of message into NetSuite. E.g. Copying text from somewhere with different formatting.
   
   This concern can occur for Standard fields as well for Custom fields. When users remove the text with CSS parameters, and users enter the correct text from e.g. Notepad, it is saved properly.
   
   
2. Regarding incorrect text in Email Alerts, this can be caused by used fields in Saved Search. E.g. Fields under Results subtab on the Saved Search.
   
   In the Saved Search users have to use the Formula (Text) fields (formula = ID of the field) instead of fields itself (e.g. Message Text, other custom fields causing the problem).

Removing the Fields from Results subtab and replacing them with Formula Text using the ID of the fields should resolve the problem.
When users receives the Email Alert, it should be with no CSS parameters.
