- Workaround
Remove branding.

[Akihiro Motoki (amotoki)]

The workaround mentioned in the bug description is to remove the branding, so it looks like an issue not of horizon but of stx-openstack. I think this is "Invalid" as a horizon bug but I would like to hear from the bug author before marking is as Invalid, so I am marking this as Incomlete.

[Thiago Ribeiro Carvalho (trcarvalh)]

You're correct, Akihiro - my apologies. I will open this for StarlingX. Thank you!
