Experiment showed the test is passing if Input.dispatchMouseEvent is dispatched BEFORE CDP event Page.lifecycleEvent.firstPaint.

I am not sure how those could be related. Note that the CDP implementation in Puppeteer passes the test.

This problem was preventing click events from being logged at all, and is not related to the specific issue mentioned.

The problem with not having the second double click is in the fact that BiDi does not have a concept of click count. As a workaround, Mapper uses a heuristic ClickContext, grouping all the clicks within 500 ms to a group of clicks. This ends up with the following CDP calls:

• Input.dispatchMouseEvent: "mousePressed", "clickCount":1
• Input.dispatchMouseEvent: "mouseReleased", "clickCount":1
• Input.dispatchMouseEvent: "mousePressed", "clickCount":2
• Input.dispatchMouseEvent: "mouseReleased", "clickCount":2
• Input.dispatchMouseEvent: "mousePressed", "clickCount":3
• Input.dispatchMouseEvent: "mouseReleased", "clickCount":3
• Input.dispatchMouseEvent: "mousePressed", "clickCount":4
• Input.dispatchMouseEvent: "mouseReleased", "clickCount":4

Could we track clickCount within a single performActions call and not across the calls?

Please see as well w3c/webdriver#1772 which might be related. Lets discuss this topic in the next monthly meeting.
