Drop Cap text not retained and dialog box glitch with settings

[nooblag]

Describe the bug
When first setting a Drop Cap paragraph style, there are bugs in the dialog box with the fields Number of characters, lines and Space to text, and the Drop Cap settings are not retained next time document is opened, even after saving.

The bug in the dialog box is that on first setting, when enabling the checkbox "Display drop caps", the fields Number of characters, lines and Space to text remain greyed out and cannot be changed until closing and reopening the dialog box.

Then when Drop Cap is finally set, all those settings are lost when document is next opened, even after it has been saved.

See screen recording below to illustrate all the above.

To Reproduce
Steps to reproduce the behavior:

1. Start new document.
2. Set Drop Cap paragraph style.
3. Save document.
4. Close.
5. On re-open, Drop Cap is not there.

Expected behavior

• When enabling the checkbox "Display drop caps", the fields Number of characters, lines and Space to text are not greyed out and accept values.
• Drop Caps remain in the document after saving and reopening.
