All dropdowns buttons in Simulator do not respond when clicked on their header name. The dropdown buttons have to be clicked on dropdown arrow specifically. Refer the attached video

Steps to reproduce:
1) Create a new project
2) Window > Package Manager > Install Adaptive performance
3) Edit > Project Settings > Adaptive Performance > Simulator
4) Click on Runtime settings (not the arrow)

Actual result: Runtime Settings dropdown does not respond

Expected result: Runtime Settings dropdown should respond even when it is clicked on it header name
