Comment after last || branch in an if clause is forced to a separate line

This code:

if lower.contains("expiry date:")
|| lower.contains("expires:") /* .am, .br, .dk, .edu, .is, .lt, .se, .ua */
|| lower.contains("expire:") /* .ar, .cz */
{
	// ...
}

is formatted to:

if lower.contains("expiry date:")
|| lower.contains("expires:") /* .am, .br, .dk, .edu, .is, .lt, .se, .ua */
|| lower.contains("expire:")
/* .ar, .cz */
{
	// ...
}

Supposedly rustfmt is assuming the comment between if and { is comment for the entire if clause. Ideally it should take || into account and take the comment before { as comment for the last || branch. (Probably also &&)

Start by reproducing the formatting change with the Rust snippet in the issue, then trace rustfmt's handling of comments between the final condition and the opening brace. Done means the comment remains associated with the last || branch, with analogous behavior considered for &&.
