incompatibility of tcmd 30 and vim9

Back in 2019, I reported that tcc while attached to tcmd makes Vim unusable. The cursor position and location of where characters are inserted are not the same.

That seemed to have been fixed for a while, but that bug is back.

tcc while attached to tcmd in version 30. Vim9 console mode is not usable. I have v 30 build 18

When I revert to tcmd/tcc 29 build 17, I do not see this problem w/ vim.

This is under Win 10 22H2
