Log-in button broken

[hermann-san]

Hi there, yesterday I did an update of nodebb (from 3.8 to 3.10.3). and now the SSO log-in button for keycloak seems to be broken. At least the link to the Keycloak icon. When I click on that empty rectangle, I can still log-in but user will be confused when the button is missing
I wonder if someone has also noticed this and if there is a workaround to fix it.
Thanks.
