See attached video. If you hover over the pocket icon in a popup window, the url bar shifts.
Which nightly is this? What version of OS X? Does this reproduce with servo/stylo disabled? How about safe mode? Clean profile with a popup that isn't from a logged-in gmail session ( I find running this in a web console helpful: document.body.addEventListener("click", () =>"", "_blank", "height=200")) ) ?

This could be a frontend issue, but equally looks like something that might be a graphics/layout issue. It'd help if we could narrow this down further, but for now, I can't quickly repro on my own OS X nightly (today, osx 10.12.6)

Ah, never mind, I need an actual URL in the window, about:blank doesn't do.

Jared, this seems to be happening because the animatable box unhides on :hover. Any idea what's up?

Or that. They both landed in the same nightly, from different branches, so that was fun... (x-ref bug 1390182 as well)

We unhide it on :hover to preload the animation. We shouldn't do this in windows with chromehidden because the toolbar won't have position:relative.

I can reproduce this on latest Linux Nightly, 57.0a1 (2017-08-14) (64-bit).

This is specific to the Pocket icon -- it does not happen with the bookmark or "..." icons.

 1. Compose an email message in Gmail.
 2. Shift-click the diagonal-expanding-arrows icon at the top right of your compose-new-message pane. (This should pop out a smaller dialog for your email message.)
 3. Hover the pocket icon in the (non-editable) URL bar for that smaller window.

ACTUAL RESULTS: The entire contents of the URL bar shift upwards by several pixels.  The .../star/pocket icons at the right side shift slightly leftwards, too.
