Example test script to reproduce

OVERVIEW:
==========================================================================================

Safari does not click on any elements in the page after issuing a moveto WebDriver command.

According to the documentation at https://developer.apple.com/library/content/documentation/NetworkingInternetWeb/Conceptual/WebDriverEndpointDoc/Commands/Commands.html both the moveto and click command should be supported.

EXPECTED BEHAVIOR:  (running against chromedriver)

STEPS TO REPRODUCE:
==========================================================================================

1) start safari driver

safaridriver -p 9515

2) serve example html page from somehwere:

<html><head><title>WebDriver test</title></head><body><label for="in">Input</label><input type="text" id="in"/><button id="click_me" onclick="alert(document.getElementById('in').value)">Click Me</button></body></html> 

3) run the attached test.py script to issue the webdriver commands that do not behave as expected.

This is probably not a WebKit bug, because safaridriver is not part of WebKit. Please file a bug report at bugreport.apple.com.

Ok Thanks Brian. 

I have raised https://bugreport.apple.com/web/?problemID=35120050 with apple to cover this issue then.
