Steps to reproduce:

1. Download attached project and open in Unity.
2. Make sure Run In Background is enabled in the Player Settings.
3. Switch the module to WebGL in the Build Settings.
4. Enable Development Build, Atoconnect Profiler and Deep Profiling Support in Build Settings.
5. Build and Run the project.
6. Once the project is built and launched, open the Frame Debugger >> Window >> Analysis >> Frame Debugger.
7. It shows that Autoconnect is the connection source.
8. Press the Enable button.

Observe: No data will be displayed. Enable button is active and the user can trigger it.

Actual results: No data is displayed when using WebGL build. Enable button is interactive.

Expected results: Frame Debugger should not allow WebGL build to be captured. Enable button should be disabled. Warning in the Console should be printed that WebGL platform is not supported.
