Memory leak when using large js library

[mopicus]

When using typescriptServices.js file, for transpiling typescript code to javascript, it appears to be a memory leak. The size of the library is ~6MB

After each call to CallGlobalFunction, the memory goes up by 30MB, and never goes down

public sealed class ScriptCompiler
{
        private readonly ScriptEngine jSEngine;

        public ScriptCompiler()
        {
            jSEngine = new ScriptEngine();

            var compilerSourceStream = Assembly.GetAssembly(this.GetType())
                .GetManifestResourceStream("typescriptServices.js");
            var compilerSource = ReadStream(compilerSourceStream);

            jSEngine.Evaluate(new StringScriptSource(compilerSource));

            var bootstrapSourceStream = Assembly.GetAssembly(this.GetType())
                .GetManifestResourceStream("nTypescriptBootstrap.js");
            var bootstrapSource = ReadStream(bootstrapSourceStream);
            jSEngine.Evaluate(new StringScriptSource(bootstrapSource));
        }

        private string ReadStream(Stream stream)
        {
            var value = string.Empty;
            using (stream)
            {
                using (var sourceReader = new StreamReader(stream))
                {
                    value = sourceReader.ReadToEnd();
                }
            }
            return value;
        }

        public string Compile(string source)
        {
            Ensure.NotNullEmpty(source, "ScriptCompiler.Source is empty");

            try
            {
                var transpileResult = jSEngine.CallGlobalFunction("tsTranspile", source);
                var outputCode = jSEngine.CallGlobalFunction<string>("getTranspileResultCode", transpileResult);
                //Need to call GC.Collect here, otherwise memory goes up by 30MB after each call
                GC.Collect();
                return outputCode;
            }
            catch (Exception ex)
            {
                return "";
            }
        }
}

Was this issue ever addressed or is it still occurring? Or was it ever an issue with Jurassic vs the specific script being run?
