ADDITIONAL SYSTEM INFORMATION :
os_x: 14.0 Beta
java: openjdk 20.0.2 2023-07-18
javafx: javafx-sdk-20.0.2

A DESCRIPTION OF THE PROBLEM :
Using a minimal JavaFX application (used from bug JDK-8283590) and starting it from the command line or eclipse shows the JavaFX window in the background. It needs two clicks into the window to bring the application to front.
This behavior is also described JDK-8283590, but it's not related to the "Secure Keyboard Entry" (which is turned off in the terminal and not available from eclipse).
Because this is not related to the "Secure Keyboard Entry" flag, this may be an new problem with ox_x 14.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Use minimal JavaFX from JDK-8283590 and run it.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Application window is in front.
ACTUAL -
Application window is not in front and needs two clicks to get activated
