I am using the toPathArray method in the following way

const jsonpathTokens: string[] = JSONPath.toPathArray(propertyRef.propertyPath);

When I pass in the string "$.subsensor.temp" for the first time, it will return ["$", "subsensor", "temp"] as expected. However when the toPathArray is called again with the same input, it returns ["subsensor", "temp"]. This happens for other inputs of a similar type.

When I stepped through the debugger it seems like there is a JSONPath.cache object which is checked before the regex is run. I checked that the value saved to the cache exprList is correct. However on the immediate next call the cache object was already modified to exclude the "$".

I think this is a bug because the toPathArray method should return the same values for the same input.

I am using v1.0.0 and I'm using the library within typescript.
