Well, Sansa was scared of ghost Jon and she was scared of that Jon stand-in tomcat. Will she be scared of Jon too?

I wouldn’t blame her Anon. Look at all the resurrected people of Asoiaf… Do they seem uwu babies that one would like to hug at first sight?

She was really scared of Ghost!Jon in the Winterfell Crypts, true. But she was already scared with the darkness and what Robb was telling her about dead men walking so she ran instantly and didn’t have time to realize it was only Jon.

That’s what exactly what happened with the tomcat, she was scared and nervous after seeing Dontos in the Godswood, so when the tomcat brushed her leg she almost faint but then she realized it was only a cat.

It is possible that Sansa will be scared of post-resurrected!Jon at first, but they are wolves from the same pack, so they will recognize each other. And as I said before, Sansa has a long training in taming beasts.

Thanks for your message.
