1593106 - [motion-1] Run transform animations on the compositor even if offset-path has no effect and other offset-* is overridden by an important rule

Status: NEW

(Core :: CSS Transitions and Animations, enhancement, P3)

Description

[Boris Chiou [:boris]]

After supporting compositor animations on motion-path, multiple transform-like properties animation doesn't run on the compositor if one of the offset-* property is overridden by an !important rule.

However, if offset-path is none and we don't have any animation on it (i.e. no visual effect and stacking context), we should still run the multiple transform-like properties animation on the compositor, instead of falling it back to the main thread.
