    @>

Problem description

The comment is lost; this is because the element representing the quotation brackets <@ @> is chosen over the element representing the quoted source simply by being first in the list, rather than being the most specific element, despite the comment in findNodeWhereRangeFitsIn.

Extra information

• The formatted result breaks my code.
• The formatted result gives compiler warnings.
• I or my company would be willing to help fix this.

The operator node in SynExpr.Quote should be ignored and not visited in

fantomas/src/Fantomas.Core/AstTransformer.fs

Lines 221 to 223 in 60fc902

	| SynExpr.Quote (operator, _, quotedSynExpr, _, range) ->
	let continuations: ((TriviaNode list -> TriviaNode list) -> TriviaNode list) list =
	[ visit operator; visit quotedSynExpr ]

It is an artificial node constructed by the parser. Removing visit operator resolved the problem.
