1047241 - [Touch Caret] Touch Caret doesn't follow input if it's focused and moved programmatically

Status: NEW

(Core :: DOM: Selection, defect, P5)

Description

[Oleg Zasypkin [:azasypkin]]

Attachment: caret_and_transition.htm

In Gaia SMS app input (in our case content editable div) is focused programmatically and then shifted down with "transform: translateY". Touch caret doesn't follow the input in this case.

I've attached reduced test case that reproduces the issue in Nightly too (with flipped touchcaret.enabled preference): just press button that programmatically focuses and applies transformation several times.

Reproduced on the latest Nightly and master B2G (Flame)

Bulk-downgrade of unassigned, >=5 years untouched DOM/Storage bugs' priority and severity.

If you have reason to believe this is wrong, please write a comment and ni :jstutte.
