Title:
  [regression] Much higher CPU during some gnome-shell operations

Status in gjs source package in Bionic:
  Triaged

Bug description:
  [Impact]

  Since fixing bug 1672297 in release 18.04 we experience much higher
  (almost double) CPU usage during gnome-shell JavaScript operations,
  such as the icon spring animation.

  [Test Case]

  Use 'top' to measure the CPU usage of the gnome-shell process while
  tapping Super+A repeatedly. It should be much lower with the fix than
  without.

  [Regression Potential]

  Low. This particular fix is tiny
  (https://gitlab.gnome.org/GNOME/gjs/merge_requests/236) and has been
  released and used in a couple of upstream gjs versions already without
  issue.

  [Other Info]

  The fix is already released to 19.04 as part of gjs version 1.54.2-1.
