What steps will reproduce the problem?
(1) Navigate to http://tinker.ruffilli.it/dombreak.htm (simple page created to repro)
(2) Open developer tools and create a DOM Breakpoint, type subtree modification on div#the-text
(3) Verify the breakpoint works by clicking the button - developers tool will now be opened at the "Source" tab
(4) Refresh the page and click the button

What is the expected result?
DOM breakpoints should work after the page is refreshed.

What happens instead?
DOM breakpoint does not work, unless user clicks on the "Elements" tab, which re-populates the DOM breakpoints from the previous session
