Instead of
StyleBox["\[LeftBracketingBar]", FontColor->GrayLevel[1]]
you can use \[AutoLeftMatch]. For example,
Cell[TextData[Cell[BoxData[
FormBox[
SubsuperscriptBox[
RowBox[{
"\[AutoLeftMatch]",
FractionBox["f",
FractionBox["g", "h"]], "\[RightBracketingBar]"}], "a",
"b"], TraditionalForm]]]], "Text"]

You can work around this by modifying the "UnmatchedBracket" style in
the Automatic Styles for the Notebook. However, using auto-matching is
better.
