🛠️ Fix T379634: Ensure Proportional Italic Font Rendering in ToC

[chandra9302]

Phabricator:
T379634

Notes

• The issue occurs when indentation level is 1 in the Table of Contents (ToC).
• At this level, the Subheadline font type is used, setting the font size to 15.
• When text is styled with bold or italic, the font type switches to Georgia3, which has a font size of 20.
• This font size mismatch causes the formatted text to appear disproportionate compared to the rest of the text.
• The issue is not specific to a single article but affects all articles’ ToC consistently.

Test Steps

1. Open JK Rowling article on EN Wikipedia
2. Open Table of contents, observe titles in "Life and career" section
