I think this worked before and I broke it the previous time I touched this code. |

This just reverts a bug recently introduced in #18309. Maybe no release notes needed. |

I've been running Visual Studio in debug mode and I noticed a lot of assertions related to cancellation.
Cancellable.CheckAndThrow()surfaces as an internal error, despite being in the context ofcancellableworkflow, for example here:fsharp/src/Compiler/Service/FSharpCheckerResults.fs
Lines 3284 to 3285 in 172dc31
This seems benign in real use, but I think is not correct. It's also annoying when trying to test things in debug mode.
The fix is to handle such things in the cancellable builder.
Update: This worked before, and I broke it. This PR just reverts relevant parts of the code.
