I left this testcase as-is, as I'm unsure if there are multiple aspects that Gecko and Blink disagree on.

Visually, Blink seems to not push the "X" outside of its containing block despite it having a left:-56px, while Firefox does. However, based on the complexity of the case I can't be sure if that's really what's going on.

This is affecting omnitv's site, as reported in

Flags: webcompat?

We're inconsistent here, you can coerce Gecko to render right toggling the left property a couple times, and also toggling the content property on the pseudo-element. This has relatively positioned inlines, so it seems likely that this bug is similar to the bugs dependent on bug 255139.

Depends on: 255139

This seems more like bug 489100 to me. See also bug 1158666.
(the "fragmentation" in this case is due to the ib-split)
