Description

There was an issue (Automattic/wp-calypso#84590) related to the theme that provides built-in fonts with limited font weights. That issue seems to have been solved in Gutenberg ≥ 17.6, but new issues have arisen. These issues are observed when installing the same font as the built-in fonts provided by a theme.

Observed Issues:

1. The built-in and installed fonts are treated as distinct fonts on the UI.
   • -> This might be the right behavior. See this comment.
2. Changes in font-weight are not immediately reflected on the canvas, requiring a page reload for updates to be visible. (It might be related to Uploaded Fonts Are Not Reflected in Editor Canvas Immediately #58765.)
3. The default font-weight provided by the theme is altered upon installing a new font variant, which should not be changed.

Expected Behavior:

• The UI should recognize and treat the built-in and installed fonts as the same.
• Font updates, especially weight changes, should be immediately visible on the canvas without reloading the page.
• Installing new font variants should not alter the default font-weight settings the theme provides.

Step-by-step reproduction instructions

• Ensure the active theme is set to Adventurer.
• Navigate to the Site Editor
• Add an H1 block with “default” font-weight through the “Appearance” setting.
• Add an H2 block with a “light” font-weight through the “Appearance” setting.
• Initially, observe both H1 and H2 using the same font weight in the canvas.
• Open the Font Library modal and install ALL font variants of the Rubik font.
• Notice that the built-in font and the installed font are recognized as two separate entities in the Font Library modal. (Observed Issue 1)
• Change the font weight again for H1 and H2 blocks and observe they still display the same font weight in the canvas. (Observed Issue 2)
• Save changes and view the site front (outside the canvas) to see both H1 and H2 displaying the updated font-weight. (Observed Issue 3 for H1)
• Reload the editor and observe both H1 and H2 now reflect the updated font weight on the canvas. (Observed Issue 3 for H1)
• Open the Font Library modal and remove the Rubik font, noticing that the font weights for both H1 and H2 do not revert to their previous states. (issue 2)
