Inherited properties are not inherited (FontObj)

[cursork]

This is a more general issue, but this issue will be closed when FontObj on containers such as SubForm is correctly handled by contained objects. The simplest reproduction case is with Label. Minimal example from ⎕WC:

  'F1'⎕WC'Form'('Coord' 'Pixel')
  'F1.FNT'⎕WC'Font'('PName' 'Courier')('Italic' 1)('Underline' 1)('Size' 50)
  'F1.L1'⎕WC'Label' 'Test one'('Posn' 50 50)
  'F1.SF'⎕WC'SubForm'('Posn' 100 50)('FontObj' 'F1.FNT')
  'F1.SF.L1'⎕WC'Label' 'Test two'('Posn' 10 10)

From a quick search, these need to be checked to see if they suffer from the issue:

• Button ✅
• Combo ✅
• Edit ✅
• Grid ✅
• Label ✅
• List ✅
• ListView ❗
• Menu - didn't seem to change in Windows
• MenuBar - as above
• Ribbon - to address as a whole
  • RibbonButton
  • RibbonButtonGroup
  • RibbonDropDownButton
  • RibbonDropDownGallery
  • RibbonGroup
  • RibbonItem
• Text ✅
• Treeview ❗

Commit c132c85 is the first stage of tackling FontObj everywhere. I get a similar result in EWC and ⎕WC for my simple example above (and for Button and Edit).

I will look at other usages of FontObj before closing. Edited description contains ❗ marks for all those trivially tested in ⎕WC to respect eg an outer subform's FontObj - so they likely need an update in JS too.
