--- Comment #22 from Pascal Blessing <pascal.blessing@gmx.at> ---
The problem with transform and position: fixed was an issue for me for quite a
long time. Luckily I was able to solve it with some kind of JS polyfill.
However, looking up the position: sticky specs I've just stumbled across the
containing block definition of CSS 3
(https://drafts.csswg.org/css-position/#def-cb) which says:

"""
If the element has position: fixed, the containing block is established by the
viewport in the case of continuous media or the page area in the case of paged
media.
"""

which would conflict with the previous definition and implementation of Chrome
(and finally resolve
https://bugs.chromium.org/p/chromium/issues/detail?id=20574)
