Issue Description

I am experiencing a problem with... format on save moving cursor to the bottom of file.

Expected Behaviour

-- Description of what should be happening --

Just like it was. Nothing happens except nice layout.

Actual Behaviour

-- Description of what actually happens --

Whenever I press Ctrl+S to save file cursor moves to the bottom of file. I started to experience this after upgrade to 1.28.1 and this is just out. It could be a bug on VSCode by the looks of it since I didn't had this behavior before.

Hope the movie is good enough

I wonder if this is related to #1154.

Obviously we don't do any explicit cursor handling, but perhaps we are not using VSCode properly?

[PrzemyslawKlys]

Just so you know.. I can't reproduce it anymore. Not sure how it started..

[Cirzen]

Appears to be same as #1507
It is intermittent, I've not yet been able to spot a pattern as to why it does / does not occur.

Closing this issue in favour of #1507
