We get conhost.exe:tty failures on testbot:
- not for version prior to w1064v1909 (these tests require
  pseudo-consoles, which are not implemented in these Windows
  version).
- for w1064v1909
- not for W10 versions after w1064v1909.

So, we assume that pseudo-console support is immature in this
Windows version: skip all the remaining test at the first
discrepancy point.
