Studio doesn't deploy the branding configuration

Hello,

We're setting up a new instance around product catalog management. All our configuration works, except for the branding for the login page: it is never applied.

Reproduction steps:

• Create a branding
• Hot-reload => The login page is not updated

I've done the following to debug, without success:

• Checking log files => no error
• Checked by browser cache => still the same
• Removed and reinstall the Studio package => nothing changes
• Removed the server temporary files (/tmp) as well as the jar in /bundles => nothing changes
• Run nuxeoctl mp-purge and reinstall everything => nothing changes
• Recreate the branding, with basic configuration (like simply removing the footer and the color of the login box) => Still the same
• Uncompressed the ZIP / Jar that is deployed => I can see my config is there
• Local nuxeo install => same issue

Happening on 10.10 with hotfixes applied

I really don't know what is happening, could you help please ?
