Bug : Linked Metrics : inverted values

with the pipe character ( | ) I would like to reference the opposite spacing value of a stylistic alternate letter.

“=|n” is working
"=n.ss01" is working
"=|n.ss01" is not working (fetches no value, stays with the pre-existing value)

( using version 1.4.3 on os-x 10.6 )

True, this seems to be a bug in the latest beta.
I cannot get “=n.ss01” to work either.

This is a quite old problem. Nothing new in the latest beta.
I fixed it.
