Original issue description

• Did you search for similar issues before submitting this one?
  Yes

• Describe the issue you encountered:
  On some pages / popups, clicks don't work:

• The autoplay permission bar on messenger.com didn't register my clicks, but started working after a browser restart. On other sites it worked.

• I've noticed clicks stop working from time to time on various pages and windows, in particular in popups: when developer tools are opened, right click doesn't work. On popups opened by OAuth pages, for example, the lastpass popup for selecting accounts with which to populate fields won't be able to spawn.

• Platform (Win7, 8, 10? macOS? Linux distro?):

OS X

• Brave Version (revision SHA):

6b5e4e2

• Steps to reproduce:

  1. Use Brave
  2. Trigger autoplay question on as many sites as possible
  3. Click any of the buttons

• Actual result:
  Eventually, the click will no longer register

• Expected result:
  Clicks shouldn't be a luxury or a lottery and should register every time.

• Will the steps above reproduce in a fresh profile? If not what other info can be added?
  Not sure, doubt it. I think it has to stay open for a while to accumulate the typical NodeJS memleak lake.

• Is this an issue in the currently released version?
  Yes

• Can this issue be consistently reproduced?
  No

• Any related issues:
  Possibly, I've been told there have been reports of non working context menus and clicks, but cannot find them.

Clearing flags as this was tested against 0.20.x, needs to be re-tested against 0.19.x.
