'Scroll Element Into View' is broken on Firefox

[Brownies]

Steps to reproduce the issue

• Open a page in Firefox such that some element is not inside the viewport
• Try to scroll to the element with 'Scroll Element Into View'

Expected behavior and actual behavior

When I follow those steps, I see... Gist with trace level log output, stack trace and sample .robot and .html files

I was expecting the element to be scrolled into view. This does work on Chromium, both headless and normal.

Environment

Browser: Firefox 103.0 Browser driver: geckodriver 0.31.0 Operating System: Linux, Ubuntu 20.04 Libraries

• Robot Framework: 5.0
• Selenium: 4.1.3 / 4.4.3
• SeleniumLibrary: 6.0.0
• Interpreter: CPython 3.8.10

A likely culprit seems to be the keyword itself which uses ActionChains.move_to_element instead of ActionChains.scroll_to_element.

Is some one following up? When this issue will be released? Once this issue is fixed we can remove the JS in our script

I'll see if I can fix this and get the acceptance tests running on Firefox too.

Bad news, switching to ActionChains.scroll_to_element does not fix the problem. It's also present with RF 6 and selenium 4.7.2 with Firefox 108. Maybe this is a Selenium or Geckodriver problem?

Yeah, this is an ancient Geckodriver issue and they will not fix it until W3C updates the WebDriver spec: https://github.com/mozilla/geckodriver/issues/776#issuecomment-355086173 Might as well close this issue because the problem is not in SeleniumLibrary and judging by the rate of recent commits the spec update is going to take an eternity.
