1973691 - Too many events from touch simulator on pages with same-origin iframes

Status: RESOLVED FIXED

(DevTools :: Responsive Design Mode, defect, P2)

Description

[Holger Benl [:hbenl]]

STR:

• open https://hbenl.github.io/test/iframe-touch/parent.html
• enable RDM and touch simulation
• open the web console
• click on the iframe and look for messages in the console

Expected:

• one message "pointerdown from child"
• one message "touchstart from child"
• one message "mousedown from child"

Actual:

• two messages "pointerdown from child"
• two messages "touchstart from parent"
• one message "touchstart from child"
• one message "mousedown from child"

To clarify, for cross origin iframes, we have the expected number of events. DevTools might be dealing with this incorrectly because we used to have only one target per origin, but there seems to also be a platform issue where synthesized events unexpectedly bubble from frame to parent.

Actually for cross origin iframes we also get two "pointerdown from child" messages instead of one but the "touchstart from parent" messages don't show up in that case.
