Function find_opt_node_in_file_compensated 

fn find_opt_node_in_file_compensated<N: AstNode>(
    sema: &Semantics<'_, RootDatabase>,
    syntax: &SyntaxNode,
    node: Option<N>,
) -> Option<N>

Attempts to find node inside syntax via node’s text range while compensating for the offset introduced by the fake ident.. This is wrong if node comes before the insertion point! Use find_node_in_file instead.
