Inline chat with multiple changes shifts focus and cursor to a suggestion on another line when invoked for multi line changes

[bhavyaus]

Found when testing #208409

Copied repro steps from above TPI.

1. enable inlineChat.acceptedOrDiscardBeforeSave (should be on by default)
2. trigger inline chat again, get to make multiple changes (e.g ask it to use the assert-lib to check that some variable is a number)
3. Observe that the suggestions shifts focus away from the active line if the first code suggestion is NOT at the current line in the editor. See below gif for repro.

As a user, this experience is jarring. We should instead present the user with changes at the current line (if any) and then provide the option to shift focus away from the current line.

Please add steps and a complete sample. This isn't about focus about positions and revealing them. Inline chat tries to reveal the best matching location (from where you are)

Updated description with repro steps. Not an issue with the feature being tested in the TPI but still related to the inline chat experience.

Agree - that's how it should work

Moving to April, I don't believe the is a regression and time is running out
