Font-family extension: Prevent removal of quotes in parseHTML

Changes Overview

Font-family extension: Prevent removal of quotes in parseHTML

Removing quotes in font-family parsing can result in invalid HTML when using font names that contain both spaces and numbers (e.g., "Exo 2").

Implementation Approach

Initially attempted to add quotes in renderHTML, but realized the issue originated in parseHTML, where quotes were being removed automatically. Addressed this issue in 1af7829 The reason for this behavior in parseHTML is unclear, so further investigation may be required.

Testing Done

All existing tests pass. Added a new test specifically for font-family values with both spaces and numbers.

Verification Steps

Run the test suite to confirm no regressions.
Verify that fonts with spaces and numbers in their names, like "Exo 2", are correctly parsed without removing quotes.
