broken indent by pipe formatting

[s-trooper]

When formatting a pipe to a line, but with a line break in a string parameter, the indentation is sometimes broken. This correct F#:

let f a b = 
    a "
" |> b

will be current formatted to:

let f a b = a "
" |> b

this would not compiling because of wrong indent. The correct version would be:

let f a b = a "
"           |> b

This issue breaks many lines of code when i trying to compile formatted version of this very project. In the moment i am not sure what to do about it.
