'enabled' assertion and text insertion issues

See original GitHub issue

Hi there,

I’m just updating some of our SAFE stack course modules, and I am finding some issues with canopy.

I have a button that is enabled when a text box has content, and disabled when it is empty.

I tried to write a simple test for this and it wasn’t working.

I found that

The enabled / disabled assertions were failing as the button is reported as notDisplayed when disabled, causing a timeout.
Emptying the text box programmatically does not trigger the onChanged event so the button remains active, however adding text does trigger it)

I have attached a sample showing these cases.

Use dotnet run in the root for the main app app.zip

I get this:

../app/Build.fsproj(10,3): error MSB4019: The imported project "../app/.paket/Paket.Restore.targets" was not found. 
Confirm that the expression in the Import declaration ".paket/Paket.Restore.targets" is correct, 
and that the file exists on disk.

If you can just give me a snippet of the line that is failing and then a snippet of the html for the control you are trying to test that would probably work.

Displayed/Not displayed checks the display tag and the opacity. Your code may be visually disabling the control in a different way and you may have to write your own custom validator for that.
