Thanks for the patch, @hareesh-pillai!

Underscore is now managed by the package.json file. The version needs to be updated in that file and the appropriate changes to the package-lock.json file also need to be included in the patch.

Thanks for your work on this, @hareesh-pillai!

I did some testing and discovered a console error. But it turns out this already exists in core. I opened #48021 for that.

Reopening to address test failures:

>> tinymce.obsolete - HTML elements non-conforming to HTML 5.0
>> Message: TypeError: undefined is not an object (evaluating 'a.replace')
>> Actual: null
>> Expected: undefined
>> file:///home/travis/build/WordPress/wordpress-develop/build/wp-includes/js/underscore.min.js:1

>> tinymce.obsolete - HTML elements non-conforming to HTML 5.0
>> Message: Expected 6 assertions, but 7 were run
>> Actual: null
>> Expected: undefined
>> test@file:///home/travis/build/WordPress/wordpress-develop/tests/qunit/vendor/sinon-qunit.js:61:21

The failures come from tests/qunit/wp-includes/js/tinymce/tinymce-obsolete.js, however renaming that file just leads to similar failures in other files.

It's also worth noting that the failures are inconsistent, sometimes I get a different message:

I was able to track down the issue to this commit cleaning up the _.debounce() function, before that commit the tests pass successfully.

Not sure what's specifically causing the issue here, I guess there's some kind of a race condition between Underscore's _.debounce() and QUnit's internal timeout handling.

I looked at this a bit today. The _.debounce() function invokes _.delay() with 4 arguments, but that function appears to only accept 3 arguments. Removing this from this line in Underscore fixes the problem. It's strange that only one are two tests are failing (and with inconsistent messages), but all of the front end functionality seems to be working as best I can tell.

Going to move this to Future Release for now since this is not a pressing change. If someone a little more familiar with Underscore is able to investigate in time for 5.3, we can move it back. But, it's possible that an upstream PR may be needed.
