Nested catch and throw do not seem to work properly

Hello All,

The following code is attempting to generate a catched error inside the 'inner' function and rethrow it to the 'outer' function so that it is catched again there.

Testing it on JSFiddle does produce the 2 Catch inner and outer to happen, it is not the case on Espruino 1v80.

Am I missing something?

function outer() {
 try {
   console.log('In outer');
   inner();
   console.log('Out outer');
 } catch(x) {
   console.log('Catch outer');
}
}

function inner() {
 try {
   console.log('In inner');
   throw "coucou";
   console.log('Out inner');
 } catch(x) {
   console.log('Catch inner'+x);
   throw x;
}
}

>outer();
In outer
In inner
Catch innercoucou
Out outer
=undefined
Uncaught coucou
 at line 8 col 10
   throw x;
          ^

There are 2 threads on this forum about catch and throw but they did not helped me...

Thank's for reading.
