Public bug reported:

Hi,

We have openstack ansible rocky 18.1.9 setup and when a user is trying
to access a vm console from web browser, they are not able to send
keystrokes properly. When for example, pressing ENTER key, the display
is broken into number of lines and not clear what they are typing in. In
the nova-spice-console logs, we are observing these messages frequently:
