Thanks for the heads up, it was discussed in the [chat](https://mithril.zulipchat.com/#narrow/stream/324076-general/topic/REM), I hadn't seen this issue... I think Heroku retired the free tier, and Leo understandably let REM disappear. A...

There's also a dead link to `brick.mozilla.io` in `.//docs/hyperscript.md` I'm removing these links from the WIP docs for the linter to pass, and mark this bug as critical so that...

Then http://leaverou.github.io/prefixfree/ is out of date (2KB, and a different design). Since it's linked from both the README and the GitHub description, I though it was current. I'll happily send...

What Safari version are you using? In v9, `stroke-dashoffset` is unprefixed, which makes it unlikely that PrefixFree is to blame. Perhaps Safari is bad at this? ``` JS [].indexOf.call(getComputedStyle(document.documentElement, null),...

I wanted to rebase this and submit it as another PR (it would have preserved @breeswish's authorship) but the branch has been deleted in the mean time, and the detached...

So, as mentioned in #8817, this happens on save. When editing the tabs are inserted properly, and then converted by the auto-formater whenever one saves.

In this case, actually, it is a false alarm. Quoting myself in the Bugzilla thread: > As it is, it will not break PrefixFree, but I don't know if it...

There's a related problem with Edge. The majority prefix is `-webkit-`, but there's a different set of `-ms-` prefixed properties. At a glance the latter are for things that are...

IE 9-11 are correctly detected as `-ms-`... Here's what a modified detector finds in Edge 13 for properties... tl;dr, the only property that exists only in `-ms-` form is `-ms-accelerator`....

We won't get away that easily :-( `@-ms-viewport`, `display: -ms-grid` and `-ms-inline-grid` do not have `-webkit-` couterparts. There's a fishy thing with the detector code, because `@-ms-viewport` is only detected...
