Steps to reproduce

Click in the button "Click me" to set a new map item

What is expected?

render something like "Symbol()" as the map key

What is actually happening?

When i try to set a new map item with a symbol key the template cannot rendering it, throwing a typerror in console "can't convert symbol to string", i could not find any information about this limitation(?) in the documentation, this is the reason why I'm opening this issue
