In my opinion, 行き過ぎた故の is not common for me, buy it seems not wrong.

As you said, I guess that ～が故に/の or Noun + 故に/の (e.g. その美しさ故に/の) is more common.<br>
However, it is almost used as literal language and We rarely use it in daily conversation.

Indeed, we occasionally use it in verbal communication.<br>
Occasionally, you want to use a literal language or difficult word, don't you?<br>
That is about it.
That is the situation in the Manga though it is grammarly wrong...
