[Bug Repot] thermometer (progress bar) produces error when trying to change its value (i.e. progress the bar)

Since the 2021 update (21.001.20135), there is an error when using multiple (overlaying) instances of the progress bar with JavaScript. Code that used to work before now generates an error.

The error is:

GeneralError: Operation failed.
Thermometer.value:1:Console undefined:Exec

To reproduce this, run the following code from the console (JavaScript Debugger):

// Define the progress bar (thermometer) as a variable for easy reference
var t = app.thermometer;
// Start a progress bar
t.begin();
// Now start another progress bar
t.begin();
// Now end the top progress bar
t.end();
// Now try to set the incremental value of the progress bar
t.value = 1;
// See the error

    That makes sense, as this issue was fixed in February 2021, see the other comments by the Adobe developers.

    I totally agree, it makes no sense. I ended up writing my own function for keeping track of the different progress bars without having to start multiple.

    I'm not getting the error message in 22.002.20191.0 (x64) Windows.

    But is it supposed to act as multiple thermometers when you call `thermometer.begin()` multiple times? Because for example, if you start a thermometer twice, you never get back to the "original" thermometer you started. With the current behavior I'd actually expect that the `t.end()` statement should close the thermometer in general, or it should restore the previous values before `thermometer.begin()` was called a second time. The current behavior is just confusing.

    ```
    // Define the progress bar (thermometer) as a variable for easy reference
    var t = app.thermometer;
    // Start a progress bar
    t.begin();
    t.text = 'Therm Level 0'
    t.duration = 50;
    t.value = 1;
    // Now start another progress bar
    t.begin();
    t.text = 'Therm Level 1'
    t.duration = 100;
    t.value = 90;
    // Now end the top progress bar
    t.end();
    // Now see that the progress set on the original thermometer are overridden,
    // But we still see the thermometer
    ```
