Foreground Selection doesn't work on Mac OS
GIMP version: 2.10.4
Operating System: Mac OS X 10.11.6
Package: Official GIMP DMG
Description of the bug
The foreground selection tool doesn't work on OS X.
Actually, it works up to the point that one can use a brush to mark the area that is supposed to be selected, but after that, neither using the Enter key nor clicking "Select" results in a selection. Both of the latter ways have been tested -- same result.
Is the bug reproducible? Always
Expected result: selection (as on Linux and Windows)
Actual result: no selection
