1520641 - Make zoom level percentage bubble animation obey prefers-reduced-motion

Status: RESOLVED FIXED

(Firefox :: Theme, defect, P3)

Description

[Yetoo Happy]

Attachment: This video demonstrates the issue that I'm having.

User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:64.0) Gecko/20100101 Firefox/64.0

Steps to reproduce:

1. Set toolkit.cosmeticAnimations.enabled to false.
2. Ctrl + Scroll fast enough or have lag on the system to cause the percentage bubble to think that there was a long enough pause between the last scroll and the next to do the expand animation. (I'm probably getting what causes that animation wrong and the sporadic behaviour of it in itself should be reported as another bug)

Actual results:

The animation which makes the percentage bubble to grow and shrink in half a second or so isn't disabled.

Expected results:

The animation should have been disabled due to toolkit.cosmeticAnimations.enabled being set to false.

:Dolske since you fixed bug 1295769 maybe you're interested in this.

Note that this pref is somewhat badly named, and it's not quite clear to me that we should in fact honor it here. See the discussion in bug 1478597 for details.
