There are a number of ways fonts can be created on macos, and there is no consistency in naming.
In MacFontFinder, all available fonts are retrieved as {name, family, file} blocks. For the name, the result of
`CTFontDescriptorCopyAttribute(fd, kCTFontDisplayNameAttribute);`
is used.

This name acts as an identifier in a number of cases, e.g. in case of `LogicalFont.getSlotForFont(String fontName)`
When the font is not yet loaded, it will be loaded via the constructor of `PrismFontFile` which will also interpret the file and set the different names. This is done in Java, and the retrieved value doesn't always match the original value obtained via

`CTFontDescriptorCopyAttribute(fd, kCTFontDisplayNameAttribute);`

As a consequence, the retrieved font is not considered the same as the requested one, and it will be put in the cache until that will overflow.
