Font face not changing in Text Overlays in the Slideshow module

Issue: In the slideshow module, add a text overlay. The font is selectable within the system's installed fonts. The font face (italic, bold, when available) can be selected but the text overlay doesn't actually change.

• Lightroom Classic Version Number: 13.3
• OS Version Number: Sonoma 14.5
  

Steps to reproduce:

1. Select a photo from the gallery
2. Go to the Slideshow module
3. Add a text overlay
4. Attempt to change the font face, e.g. select Italic.

Expected result: The text overlay chanegs to italic
Actual result: The text overlay remains in the Regular font face.
