Combine Google Fonts option prevents font effects from being applied in the UI

[hanna-meda]

Describe the bug
While Google Fonts Optimization option is enabled, font effects specified in the Google Fonts API are not applied in the UI.

To Reproduce
Steps to reproduce the behavior:

1. Activate WPR version 3.9.5 or higher.
2. Visit a page using Google Fonts API that includes font effects, e.g.:
   https://fonts.googleapis.com/css2?family=Roboto|Lobster|Tangerine|Montserrat&effect=fire|fire-animation|neon|3d|shadow-multiple|emboss|anaglyph
3. Observe that the fonts load, but their effects (e.g., fire, neon, 3D) are not applied.

Notes:

1. Font effects are applied correctly on ?nowprocket visit of the page or when Disable Google Font Optimization helper plugin is activated.
2. Font effects work as expected in WPR version 3.8.8 or below.

Expected behavior
Font effects should function as intended and not be blocked or altered by the “Combine Google Fonts” optimization option.
