except that the font will be loaded anyway, regardless of whether it is on the page or not.

2 points:
If someone has scripts disabled, you should include the font as standard and wrap it in <noscript>.
If you change your font file that you load into localStoragethe browser, it will not understand and will not update. Therefore, you need to improve the code by reference by adding a file version check.
