Pressing Cancel selecting a directory from a file dialog returns directory

[ericwinger]

In Pharo 13, executing this code in a Playground opens a modal dialog with the opportunity to select a dialog.

| path |
path :=  StPharoApplication current selectDirectoryTitle:
	         'Choose directory'.
path 

However, if I press Cancel, a FileReference is returned. I expect that nil should be returned so I know that the user canceled the operation and my application can act accordingly.

Please let me know if there is a different way I should select a directory in Pharo13.

I also tried the following expression but it gets an error Instance of ByteString did not understand #exists because an expected FileReference was a string.

UIManager default
		        chooseDirectory: 'Choose Client Library Directory'
		        from:
		        '$HOME'
			        asFileReference.

Tx for your report.

I checked and I have the same behavior in Pharo 14 - which looks wrong to me.
