I don't think the behaviour for conhost is right. We should either leave UserDefault as an alias for BlinkingBlock, which is at least compatible with the DEC standard, or we should try and map it to the actual user preference (which I'm honestly not sure how to do). Worst case we could possibly map it to blinking legacy, which I think is the system default. But as it stands, it looks like you're going to get non-blinking legacy, which is neither one thing nor the other.

Edit: Sorry this is essentially a long-winded dup of DHowett's comment.
