Describe the bug

OOM when a new interval starts before the last interval finished its callbacks.
For example, if my plot has way too many points so it never finished displaying, and the next interval kicks off before it is finished

---

Expected behavior

I would expect that when an interval does not finish either:
(a) subsequent intervals would be skipped until the original interval finishes
(b) or, the memory/variables of the original interval is released before the new interval starts

Perhaps this could be configurable

Screenshots

Memory seems to spike when an interval cannot complete within the refresh time, and pressure decreases when i kill the dash server process
