Can't paste password into Sign In form of Parallels Access

Is this normal/expected behavior?

If so, it's annoying because I use secure, generated passwords and preventing pasting is generally considered *less* secure since users are more likely to use something easy to remember and type if they can't paste from a password manager.

 

Seriously... I detest silly actions such as this... When I created my password I was able to copy/paste but when I attempt to log in using this password I am prevented from doing so??? Frustrating...
