Copilot indentation

I have been enjoying using copilot with F#. It writes routine code really well.

Copilot fails to indent code properly when starting on an empty line with the cursor indented.

A typical case is:
- Write some code and press return. The F# editor place the cursor on a reasonable line although no actual spaces are added yet.
- Copilot makes a suggestion in grey.
- Press tab. This inserts the suggestion, but the first line of the suggestion doesn't have the indent.

This gif shows copilot correctly writing a serializer line, but 1. with incorrect spacing in normal use, 2. with incorrect spacing after manually moving the cursor to the start of the line, 3. with correct spacing after manually typing in spaces before accepting.
