Bug description

Serving the provided project with mkdocs does not expand custom variables in the title bar when scrolling down to the first section of pages:

Maybe It is simply not supported or I'm using it wrong, but I was wondering if it could be fixed ? I could simply use the text manually without a variable but in our main project we try to put variables everywhere we can as some names are repeated all over the places in various pages level 1 header. Variables can't be used in the mkdocs nav section (I think) so I don't really want to use the setp of 1 of the following priorities for title page: https://www.mkdocs.org/user-guide/writing-your-docs/#meta-data And as I describe it here steps 2 and 3 seems to not work with custom variables.

Thanks !
