It's not only against COM but also SSH.
#355 added empty cancel implementation to SSH and COM.
It should not.
The idea is to not show cancel button if a session does not support cancel (no such function).
See https://github.com/sassoftware/vscode-sas-extension/blob/main/client/src/commands/run.ts#L141
I heard that @smorrisj will be implementing cancel for COM so will defer to him. If we don't support cancel on SSH, the function should be removed.

Cancel supported for local 94 with #592
