Tests are failing when parsing in non-strict mode

[afri]

When I patch up lezer-generator/test/test-parse.ts to parse files with {strict:false}, then many of the javascript tests fail.
E.g. expression/Arrays yields:

  2) expression
       Arrays:
     Error: Expected ArrayExpression in ExpressionStatement, got AssignmentExpression at 0 
Script(ExpressionStatement(AssignmentExpression(ArrayPattern("[","]"),⚠),";"),ExpressionStatement(ArrayExpression("[",String,"]"),";"),ExpressionStatement(ArrayExpression("[",String,",","]"),";"),ExpressionStatement(ArrayExpression("[",String,",",VariableName,"]"),";"),ExpressionStatement(ArrayExpression("[",",",VariableName,"]"),";"),ExpressionStatement(ArrayExpression("[",AssignmentExpression(VariableName,Equals,Number),"]"),";"))
