in my cases click on shadow DOM element spend a lot of time
it took a lot of time to execute WebUI.click() like below. (31.218s)
I suppose you have “Default wait for element timeout” to be 30 seconds.
WebUI.click() actually failed to find the element to click, waited for 30 seconds as specified in the setting, then returned. It took 31.218seconds.
Thank you very much, it helped <3
