Running tests in-line breaks external tool

Hi,

I am having a problem running JUnit tests in-line (clicking on the small arrow in picture) 
My tests are configured to run a 'make' command as an external tool before the tests are executed.

The external tool is configured to run the make command in the project root directory. 

This all works perfectly fine if I use the 'Run' command at the top of the window to run the test.  

For some reason the in-line triggering of the tests doesn't seem to pick up the working directory of the external tool and the make command fails. 

If I run the test in-line it fails and then if I simply click the 'Run' button at the top of the screen with the configuration already loaded by the in-line triggering, it works and my tests execute correctly.

It seems like there is a bug to me, that the working directory of external tool is lost? Hopefully that all makes sense! :)
