That's because JSC::Debugger expects a call to incNumberOfBreakpoints when the client needs the runtime to capture debugging information. Otherwise there will be no call frames available when the DOM breakpoints are triggered. 946903 1 webkit-bug-importer 2013-11-04 17:05:21 -0800 <rdar://problem/15389268> 947238 2 timothy 2013-11-05 10:05:51 -0800 Are you looking to add UI for DOM breakpoints? 947336 3 achicu 2013-11-05 13:52:15 -0800 I (In reply to comment #2) > Are you looking to add UI for DOM breakpoints? I don't have any plans on this yet. I was working on https://bugs.webkit.org/show_bug.cgi?id=123516 when I've discovered this issue. I'm touching some of the Inspector instrumentation and I thought I need to add a test for this case too. It took me a while to figure out why the protocol test was not working, so I've added this bug to track the issue. 1456739 4 hi 2018-09-05 09:43:00 -0700 I can confirm that DOM breakpoints are working without JS breakpoints.
