Wrong mimetype for font attachment with mkv toolnix gui

I'm using windows release.

Release 87.0 is ok. But release 88.0 is wrong.

When attaching font resource using MKVToolNix GUI the automatic mime detection is application/x-font-ttf or application/x-font-otf.

While in older versions the mime was (correctly) font/ttf and font/otf..

Also, in mime selection box there is no font/ttf or font/otf available.

I saw that mime types comes from qt and version 88.0 is using qt 6.7.3, while version 87.0 uses qt 6.7.2
