Chrome Version: ToT
OS: Tested on Ubuntu x64, but I think this can happen on all desktop platforms

What steps will reproduce the problem?
(1) Apply patch https://chromium-review.googlesource.com/c/600149 just to see the 'outlive time' of documents (the time means how many GC happens after the document is shut down and before the document is actually destroyed)
(2) Open the attached html
(3) Search any word in the page like 'search' (don't close the search window)
(4) Reload the page like 20 times
(5) Search any word again and close the search window
(6) Reload the page again
(7) See the UMA 'Document.OutliveTimeAfterShutdown.DestroyedBeforeProcessDies' at chrome://histograms and see the result

What is the expected result?
The numbers in the UMA should be less than 10 or so.

What happens instead?
The number can be larger than 10: this is almost same as the number how many reload happens. It looks like the document of the first search survives until the next search happens.
