FontDocument

Remarks

⚠ The face is loaded here and disposed with the document. FontFace owns native memory, a panel's factory runs again on every reopen, and a face loaded by a view would leak one per reopen — which for a font is megabytes.

⚠ A face that will not load is reported and the document still opens. Editing the chain of a font whose primary has been deleted is exactly when somebody needs this panel.
