WiX, Maximum recommended length of Tooltip attribute is 50 characters

When building an installer with WiX (Windows Installer XML) 3.5, you may encounter the following warning:

warning LGHT1076: ICE03: String overflow (greater than length permitted in column); Table: Control, Column: Help, Key(s): ....

This is because the Control@Tooltip value is too long. It stops giving out when the length is 50 characters or less.

Interesting fact that even with the warning, with string longer than 50, it still adds it to installer and uses the tooltip in UI.
