Enum members revert to initial value on decompile

[ganicke]

Found in micro:bit radio-broadcast lib from pxt-common-packages. Issue is filed here since it looks like a problem with the enum helper.

Describe the bug

The RadioMessage enum value connected to the radio.sendMessage block will revert to the initial value of message1 on decompile even though a different one is set.

Example:

The blocks show message1 when Hello and Goodbye are in the original code.

Expected behavior

The blocks contain the originally selected enum value.

Here's the test code to copy:

enum RadioMessage {
    message1 = 49434,
    Hello = 49337,
    Goodbye = 16885
}
input.onButtonPressed(Button.A, function () {
    radio.sendMessage(RadioMessage.Hello)
})
radio.onReceivedMessage(RadioMessage.Hello, function () {
    basic.showIcon(IconNames.Heart)
})
input.onButtonPressed(Button.B, function () {
    radio.sendMessage(RadioMessage.Goodbye)
})
radio.onReceivedMessage(RadioMessage.Goodbye, function () {
    basic.showIcon(IconNames.Scissors)
})
