This was the underlying cause of the restyle_hints_state.html failure.
It was uncovered only when fixing the HAS_EDGE_CHILD_SELECTOR flags because this
was the series of events happening.
* <script> starts executing.
* All the restyle hint processing takes place.
* <script> ends executing, gets appended to the body (I think this is also a bug).
* <body> receives children_changed notification, with an Append mutation.
* <body> had the HAS_EDGE_CHILD_SELECTOR flag, so due to its bogus value, it
restyled the whole tree after <body>, fixing any mishandling of restyle
hints.
Fix absolute-flow's auto positioning
<!-- Please describe your changes on the following line: -->
If an absolute positioned flow has no top, bottom, left, right property, its hypothetical box position should be the margin-end of its previous sibling, not the border-end.

Fix the currently logic that a item will freeze if it should
grow(shrink) and its basesize is less(more) than its min(max) size. Also
fix the divide by zero error when an item should shrink but it has zero
length and zero min size.
Add a modify_style_for_anonymous_flow() function to use initial values
for non-inherited properties and parent values for inherited properties
as the block style. It also set border and outline to zero and set the
display property from the parameter.
Support the `flex` and `flex-flow` shorthand properties in
servo. Currently they are marked as experimental, so they are added to
'__dir__.ini'.
Thanks SimonSapin and jdm for help :)
This is a fixup for `align-self`, the computed value of which should now
properly inherit `align-items` value of its parent. Additional passed
tests is also removed from ini folder. Fixup for geckolib errors.
Add the remaining longhand CSS properties of flexbox for servo,
including `flex-wrap`, `flex-grow`, `flex-shrink`, `justify-content`,
`align-items`, `align-self` and `align-content`.
tests for the remaining longhand properties are also enabled. Test for
default value of `align-self` is modified because the new default value
for this property is "auto" is current flexbox CR.
