In SB6 2560:

Given the string '(text1),(text2)' split on first occurrence of '('
returns 'text2)' as the portion after the first occurrence.

I consider that to be the portion after the 2nd occurrence of the source
string.

My workaround is to prefix a character other than '(' to the source.
However, I consider this a bug.
