It looks like "web fonts" in general are poorly implemented. You can recreate the problem with just a text box and font styling CSS.
If you look at some of my other comments in this tree you will see screenshots of the same text box with and without the local fonts installed. Presumably when local fonts are installed the OS handles everything, without the browser and the noto-fonts definition file gets in the way.
