When I debug javascript and remove a breakpoint why do they come back after a reload?

I'm debugging some javascript and I set a breakpoint on a line. When I step past it and remove the breakpoint (or remove all breakpoints), edit the javascript, and do a reload the removed breakpoints can come back in the list.

Hmm, I understand why they come back after a reload normally, but not if you have removed them. ??

Since we seem not to be able to explain this here, if the problem persists, could you ask on the DevTools forum:

Thanks.
