[Blocking Requested - why for this release]: Having a disgraceful animation on one of the core app affecting this happy path, doesn't seem compatible with the fact that 2.5 is labeled as a quality release. Hence, I think we should hold this release on this issue.

Repro rate: 5/5 on multiple websites.

Not sure this issue will show on the Flame. QA wanted for a potential branch check though.

Thanks! This was driving me crazy but I couldn't nail down the STR.
No idea how to fix it yet, but still, a solid STR is a very good first step :)

This issue seems to be specific to Aries devices.  It does not reproduce with the latest Nightly Flame build or one with a Spark gaia flashed it it.

This issue is verified fixed on the latest Spark 2.5 build.
When opening a new tab after scrolling in the browser, transition looks smooth and proper.
