What is the test for setting aside a verdict for misconduct in a civil case?

People v. Majors (1998) 18 Cal.4th 385, 417, 75 Cal.Rptr.2d 684, 956 P.2d 1137 ( Majors ).) [When alleged juror misconduct] involves the receipt of information from extraneous sources, the effect of such receipt is judged by a review of the entire record, and may be found to be non-prejudicial. The verdict will be set aside only if there appears a substantial likelihood of juror bias. ( People v. Danks (2004) 32 Cal.4th 269, 303, 8 Cal.Rptr.3d 767, 82 P.3d 1249.)
