Exception handling 'with' clause using drop-through is malformed

[SteveGilham]

Description

Code like this

  let internal ImageLoadResilient (f: unit -> 'a) (tidy: unit -> 'a) =
    try
      f()
    with
    | :? BadImageFormatException
    | :? ArgumentException
    | :? IOException -> tidy()

becomes malformed

let internal ImageLoadResilient (f: unit -> 'a) (tidy: unit -> 'a) =
    try
        f()
    with :? BadImageFormatException
    | :? ArgumentException
    | :? IOException -> tidy()

Repro code

Here at v2.9.2

Also happens at the 2.9.3 preview; the 3.0.0 level preview of the tool simply faults.

3.0.0 tool fault was caused by unrelated issue on tool side (incompatible version of FSharp.Compiler.Service and FSharp.Core), it is fixed now. 3.0.0 repro

[nojaf]

Should be ok now.
