Eoghan Murray acffc1a1e2 Replay fix for Firefox — add <head> and <body> separately (#1133 )

* Firefox fix: Allow the <head> and <body> to be added in two stages so that (presumably) stylesheet rules are ready to be applied when the body appears

The css which triggered the bug was simply

{
  margin-left: 220px;
  transition: margin-left .448s;
}

* Add a test case which can only be appreciated if you record against this file://, save the events to a html file, and then open the file in Firefox (without this PR applied)

* Apply formatting changes

* Ensure we don't apply this branch when using rrdom, where it is not necessary

* Apply formatting changes

* Rewrite insertion in order to be compatible with rrdom

Also easier to understand

* Delete transition.html

* Create grumpy-ways-own.md

patch

Fix: CSS transitions are incorrectly being applied upon rebuild in Firefox. Presumably FF doesn't finished parsing the styles in time, and applies e.g. a default margin:0 to elements which have a non-zero margin set in CSS, along with a transition on them.
