Hello, thank you for bringing this up.
This will be tackled by dotnet/fsharp#12691.
In that PR we have the original keyword information.

In that PR we have the original keyword information.

That PR is already merged. Will fantomas 4.7.x have a fix for this at some point? Or we gotta wait for 5.0?

[nojaf]

This will be a 5.0 change.
There are no plans to upgrade the FCS anymore in the 4.7 series.
