Item test form allows setting Value for testing (or receive the value from Host). This value is always truncated to 65K characters in item testing form. This produces inconsistency when data collection is working fine, but the item test doesn't allow such values.

If values are collected from the host, a negative character count could be shown in the value popup in the case of 65K+ characters.

Additionally, if test data is retrieved from host through Proxy, values received from the host are always trimmed to the 65K producing errors.
