Librewolf not working with CSD (Client Side Decorations) disabled

First, thanks for your work of making Firefox more private for the masses 😃.

I'm using the latest LibreWolf-bin build under EndeavourOS with the XFCE DE.

Other apps like LibreOffice or Firefox don't seem to have that issue? Do you know if this can be fixed?

Thanks!

EDIT: Choosing "Title bar" in the customize option solved my problem
