ecmascript Map.keys not iterable on cordova

[benstrum]

When trying to iterate Map.keys() on cordova browser, an exception is thrown "Keys is not a function or its return value is not iterable".

To reproduce the problem, run a meteor cordova app in the debugger using Chrome DevTools. From the js console, you run the following code:

t = new Map();
t.set(1, '1');
t.set(2, '2');
for (docid of t.keys()) console.log(docid)

I'm running into this issue as well. I cannot modify the runtime code since it's importing from an external library that is using this particular syntax.

Is there a workaround or fix that can address this?

Hi,

this seems pretty much related to #13094 that we just opened and has this impact: Google Maps API will stop working soon on Cordova.
