Description
while trying to return a Symbol (like following script) from execute sync command, I realized the Symbol will be serialized into an empty object.
return Symbol(1);
Based on the internal JSON clone algorithm, if the value is a Symbol, it will run to the last Otherwise branch. Thus, IIUC, it will get into clone an object and end up returning an empty object.
However, JSON.stringify(Symbol(1)) returns undefined. It's not serialized into an empty object. So, I wonder if we should serialize Symbol values to null (like what undefined is serialized) as well?

Research direction
Start by reading the WebDriver internal JSON clone algorithm and its clone-an-object branch, then compare that behavior with JSON.stringify(Symbol(1)) and the execute sync command described here. Determine the intended serialization for Symbol values and update the relevant WebDriver specification text; done means the algorithm and expected result are unambiguous.
