Hey!
Thank you very much for reporting the bug ... I checked what you wrote to me, and actually I found the problem in Construct 3 runtime 3 (instead, I didn't encounter any problems with runtime 2) ...
I fixed the bug, and now the updated and correct version is available for download ... I invite you to download and install.
I also added a very small capx to test the specific problem.
thank you very much again for reporting and for using the behavior.
Happy coding!
