I currently have a web application that can read and write files on a Samsung Tizen TV v2.4 (Firmware: T-HKMLAKUC-1006.4)

Append hover does not seem to work.

I can do the following with no issues at all: 

```
tizen.filesystem.resolve('documents/log.txt', (file) => {
    file.openStream("w", (fs) => {

        fs.write('Tizen .. '); // Works

        console.log('written to log Tizen ... '); // View if its running the code block

        // This block is ran as i get the console log from this function

    }, (e) => {

        console.log("Error " + e.message);
        // No Errors thrown

    }, "UTF-8");
}, (e) => {

    // No Errors thrown

}, "a");

```

If i change the 'w' to 'a' which should append to the file the file is empty

```
tizen.filesystem.resolve('documents/log.txt', (file) => {
    file.openStream("a", (fs) => {

        console.log('written to log Tizen ... '); // View if its running the code block

        // This block is ran as i get the console log from this function

        fs.write('Tizen .. '); // When i read it nothing here

    }, (e) => {
        console.log("Error " + e.message);
    }, "UTF-8");
});

```

Has anyone else seen this issue? Thanks

If i monitor the console logs from this function i get the following:

```
4:59:21 pm | YaBRm3kxLCctUNmhl034oLe0QQA= | "" // View the file

4:59:21 pm | YaBRm3kxLCctUNmhl034oLe0QQA= | "running append to file" // Run the append function
4:59:21 pm | YaBRm3kxLCctUNmhl034oLe0QQA= | "written to log Tizen ... " // Append function shows its running the success block

4:59:22 pm | YaBRm3kxLCctUNmhl034oLe0QQA= | "Tizen .. " // View the file (and its appended)

4:59:23 pm | YaBRm3kxLCctUNmhl034oLe0QQA= | "running append to file" // Run the append function again
4:59:23 pm | YaBRm3kxLCctUNmhl034oLe0QQA= | "written to log Tizen ... " // Shows its running the append function correctly
4:59:24 pm | YaBRm3kxLCctUNmhl034oLe0QQA= | "" // View the file and its empty

```
