[anon-block-removal] An outside list marker makes its list item's children
inline
https://bugs.webkit.org/show_bug.cgi?id=321343
<rdar://problem/184380304>
Reviewed by Antti Koivisto.
An outside marker takes no part in the list item's in-flow layout, so it must
not turn childrenInline() on.
Letting it puts a list item whose content is a block level box onto the inline
path, where the marker takes a
line of its own and the block starts below it -
<ul><li><div>text</div></li></ul> is 58 tall instead of 40.
Nothing rebuilds anonymous wrappers on this path, so childrenInline() also has
to be recomputed when a child
is detached. A marker changing from inside to outside is destroyed and
reattached, and the bit the inside
marker turned on would otherwise stay on.
