STR:

  1. Enable about:config pref layout.css.linear-easing-function.enabled
  2. Navigate to https://ffx-devtools-linear-animation-timing-function.glitch.me/
  3. Launch inspector
  4. Select the div with linear(...) animation enabled with id linear
  5. Go to the Animation tab
  6. Pause/Unpause the animation

Expected Behaviour: The element should pause and unpause close to the location it was at when the command was issued. This works for cubic bezier.
Actual Behaviour: The element jumps to locations seemingly unrelated to where it was.

Depends on: 1764126

If you highlight the div (Which doesn't match the actual div as per bug 1776422), that matches the location the div jumps to.

Depends on: 1776460
