CaseStatement is currently written as

CaseStatement:
    case ExpressionList : Statement

Here the grammar refers to ExpressionList, described as a ',' separated list of Expression.  However, Expression is a ',' separated list of AssignExpression. So this is highly ambiguous.  There's no way from the description to distinguish between AssignExpressions that should be evaluated and ignored, and cases to be handled.

If we define:

ExpressionList:
        AssignExpression
        AssignExpression , ExpressionList

then the problem goes away.  The text should be adjusted to match.
