Yeah. When we get to the line of code in question (in https://www.pinko.com/on/demandware.static/Sites-pinko-us-Site/-/en_US/v1714430179241/js/main.js , function defined as `key:"parseTransition",value:function(t){...}`), old/working Firefox has the following in `e.transition`: ``` "transform 0.3s cubic-bezier(0.645, 0.045,...

For what it's worth, though, WebKit trunk (Safari Tech Preview & gnome-web/epiphany) matches our behavior; they omit `0s` at the end of the serialization for `transition` here, and they hit...

And per https://github.com/web-platform-tests/wpt/issues/43574#issuecomment-1852190860 it sounds like Chrome is going to change too, so this is a case where the site is depending on a legacy behavior that everyone had ~6...

I added a note in bug https://bugzilla.mozilla.org/show_bug.cgi?id=1878758 , but at this point I think we should just consider this a case where the site's depending on a Chrome bug (which...

Thanks! That helps us skip past the "how do we get in contact with someone at the company involved to get this addressed" part. :) Hopefully your internal outreach is...

FWIW this seems to have led to consistent "near misses" of getting any aligned runs (for stable browser channels) for the past 9 days -- right now https://wpt.fyi/runs consistently shows...

Note that even for users who don't have any particular special configuration, **`requestAnimationFrame` does not guarantee a consistent frame rate**, and users presumably will see occasional unexpected hiccups (speedups/slowdowns) with...

Here's a screencast showing this bug in action: [screencast of bug.webm](https://github.com/metafizzy/flickity/assets/426803/6da30c5a-186d-40d2-b84e-574d949af645) (The bug is in the latter half of the screencast, after I toggle Firefox's `layout.frame_rate` pref in about:config.)

> It seems that Flickity isn't tracking how much time passes between requestAnimationFrame calls, to ensure a consistent animation duration and animation speed. Grounding this in the code a bit:...

> For me, in Firefox 126, with layout.frame_rate set to 1, I'm seeing full-speed animation when I click the previous chevron Closing the loop on this: as discussed in https://bugzilla.mozilla.org/show_bug.cgi?id=1894842#c11...
