suppress {es5Strict} does not work

[eustas]

File example.js:

/** @suppress {es5Strict} */
function hello() {
  var a = "\306";
}

Command: java -jar closure-compiler.jar example.js

Output:

example.js:3:10: WARNING - [JSC_INVALID_OCTAL_LITERAL] This style of octal literal is not supported in strict mode.
  3|   var a = "\306";
               ^

function hello(){};

Can you confirm the version of the compiler you are using?

[eustas]

closure-compiler-v20210106.jar going to try a newer one (if any)

[eustas]

closure-compiler-v20210302.jar has the same problem

Ok, with strict mode input this is a parse error and thus not suppressible.
