Windows cmd.exe terminal buffer written over

[ArneBachmannDLR]

Hi,

this is a repost of https://github.com/nschloe/tiptop/issues/63 as the issue is likely stemming from Textual:

Inside Windows' cmd.exe, a part of the terminal lines buffer is written over when exiting tiptop.

This happened when I quit tiptop via Ctrl+C, but also when pressing q: I can only see commands of the shell history from around 30 lines up/ago, but not the ones that were under the Textual application just before starting titop, as the screen buffer wasn't restored when quitting tiptop.
