Description Ryan Reno 2023-09-09 11:21:52 PDT

If you click "All Paths To" button for an object it will be added irreversibly to the All Paths To... section of the UI. This, depending on the GC snapshot, could create tens of thousands of DOM nodes which could easily eat up multiple GB of memory and cause the process to be killed even in the foreground. There should be a mechanism to remove an object from the All Paths To... part of the UI in order to let these nodes get garbage collected if they're no longer of interest.
