Reviewed by Antti Koivisto.

Inline box start/end markers with non-default unicode-bidi values do not participate in bidi reordering (they don't
inject control characters to initiate isolation/embedding). We also set their bidi levels to opaque to ensue ICU does not get confused while
running reordering.
However inline box start/end makers with injected control characters (e.g. <span style="unicode-bidi: isolate">isolated</span)
should keep their ICU assigned bidi level values for reordering.
