1950252 - scrollIntoView-sideways-lr-writing-mode-* and scrollIntoView-sideways-rl-writing-mode-* WPTs fail in Firefox

Status: RESOLVED DUPLICATE of bug 1789464

(Core :: Layout: Scrolling and Overflow, defect)

Description

[Daniel Holbert [:dholbert]]

We fail pieces of these WPTs:
https://wpt.fyi/results/css/cssom-view/scrollIntoView-sideways-lr-writing-mode-and-rtl-direction.html
https://wpt.fyi/results/css/cssom-view/scrollIntoView-sideways-lr-writing-mode.html
https://wpt.fyi/results/css/cssom-view/scrollIntoView-sideways-rl-writing-mode-and-rtl-direction.html
https://wpt.fyi/results/css/cssom-view/scrollIntoView-sideways-rl-writing-mode.html

The failure messages are all something like these:

scrollIntoView({"block":"start","inline":"center"})
scrollIntoView({"block":"end","inline":"end"})

Presumably our scrollIntoView implementation doesn't support vertical writing modes or something along those lines.

hiro mentioned that this might be related to (or partly explained by) bug 1789464.

This was just a subset of the wider issue with scroll target directionality, handled in bug 1789464.
