Event Listener Breakpoints in devtools is missing "message" |
||
Issue descriptionThere's no way to listen for incoming post message events in the devtools, this makes debugging iframe and worker code painful since you can't instrument all of the incoming messages. It seems like under Window there should be a "message" event type, or a new section if we want to also allow blocking on MessagePorts. I'd settle for Window to start though. :)

Not sure if this is related, wanted to check before I create a new issue: I'm having an issue on v54.0.2840.16 which is not an issue in previous versions. I have a webpage with an iframe in it. I trigger a message to background.js in an extension from a (native?) script (not a content script) in the iframe. The background.js process catches that message as an externalMessage. Then, a new message is triggered from background.js to content.js running in the tab, which I assume should be targeting the parent page of the iframe. The parent page content.js is not receiving this message. If I load the iframe page as a standalone in the browser, it works. This was working with the iframe just yesterday, but suddenly stopped today in beta version. Any thoughts?

Nick, it seems like this is a different issue. Can you open a separate issue and include a simple repro? Thanks.
