steps to reproduce, and a workaround-patch

I tried using lldb.exe from the llvm-mingw-nightly package.
It kind of works, can attach to process, create breakpoints,
stops at breakpoints, shows source.

But one thing I noticed is when hitting a breakpoint and when entering
the first character of the next command,
the cursor jumps a few lines upwards.
By that the output of the next command gets mixed into the previous output.

This happens in both, plain kde-plasma konsole and wineconsole.

From my debugging attempts it looks like in update_read_output
the edit_line's home_y got not updated by lldb.exe printing some lines.

Attached file contains my steps to reproduce it with
a debian trixie and with winehq packages.
At the end there is a workaround I found working well for my purposes.

I selected the component programs, because it looks to be about conhost.exe.
