Hi,
There seem to be a proble with some active frames which aren't listed as target (neither via chrome.debuggrer.getTargets nor with the CDP's Target.attachedToTarget event).
For example, this
page contains two iframes. The first one doesn't seem to register as a target with CDP and doesn't appear as an item in the results of chrome.debuggrer.getTargets. The second iframe does.
The problem seems to be with the particular source as changing it fixes the problem. Though the content runs fine though, even the pages JS code.
Any idea what could be the problem? it seems like a bug.
