This test does fail for me, locally, but unfortunately I think that's actually expected behavior? The first prompt printed by mongosh in response to the .writeInputLine() call is a regular prompt, not a multiline prompt, but that's happening because the first line of the writeInputLine() argument is empty/whitespace-only.
That being said ... yeah, there's a good chance that that causes the flakiness in the FLE test at least. I feel like it's probably a good idea to just always .trim() the input to .writeInputLine()? For raw input, there's always .writeInput() itself

Great catch! Trimming the input to writeInputLine fixed the issue 👍

For now this PR adds a failing test demonstrating how writing a multiline command prints an extraneous prompt before multiline dots (the "..." prefixed after every line-break in the input).
Arguably not a huge bug, but I do believe it's the reason for this comment:
mongosh/packages/e2e-tests/test/test-shell.ts
Line 193 in d3e2935
And the systematic failure on #2171
