[Bug] Terminal dimensions not detecting correctly with hyper.is

Using hyper terminal (https://hyper.is/) on Windows (WSL2 and CMD.exe), should be able to replicate with Windows/Linux/Mac since huper.is is cross platform, I SSH to vert.synchro.net - I've used both Fira Code and Cascadia Code font families.

During login, my screen size is not detecting properly...

System          : Vertrauenscreen: 78x17 > 80x10

If I go to user Defaults (D) then Terminal Dimanesions (L), it does seem to detect correctly.
