Original Pull Request: https://github.com/microsoft/terminal/pull/17884

State: closed
Merged: Yes

Without a VT "renderer" there's no implicit output anymore when
calling ClearPseudoConsole. The fix is trivial, but it works
slightly different from before: Previously, we would preserve
the line the cursor is on, while this PR doesn't do that.
I felt like there's not much merit in preserving the line,
because it may be a multi-line prompt which won't work with that.

Closes #17867

Validation Steps Performed

Bind 3 different actions to the 3 variants of "Clear buffer"
and test them. They work. ✅
