Hi Actipro
When I set the IHighlightingStyle.FontFamilyName to an invalid value (e.g. "Cooper Black"), I get an unhandled exception in TextLineNumberMarginBase.CheckForAssetCacheUpdates:
An unhandled exception of type 'System.ArgumentException' occurred in WindowsBase.dll
Additional information: '' is not a valid value for property 'FontFamily'.
This crash only happens when Line Numbers are visible. If Line Numbers are not visible and we set this invalid FontFamily value, the editor is able to display a backup/default font.
