isInComment
public static boolean isInComment(com.intellij.psi.PsiElement element)
- CommentUtilCore.isComment fails if element inside comment.
Also, we can not add KDocTokens to COMMENTS TokenSet, because it is used in JetParserDefinition.getCommentTokens(),
and therefor all COMMENTS tokens will be ignored by PsiBuilder.

element -
