Twenty Twenty: Chrome displays glyphs instead of "Hoefler Text" or fallback fonts

[jaruzek]

In macOS Catalina, using Chrome 79, fonts in both the block editor and frontend display as Glyphs, rather than readable text.

Disabling the following fonts rectifies this: NonBreakingSpaceOverride,"Hoefler Text"

It appears that "Hoefler Text" is the contentious font in my case, despite it not being installed on my system.

My initial suspicion was that it was was due to the following fonts, which may still have some relevance: -apple-system, BlinkMacSystemFont

What I expected

• Fonts in Twenty Twenty to render in a human-readable fashion

What happened instead

• Fonts rendered as glyphs
• Text became legible after editing/turning off font stack, as per the screenshot above

Browser / OS version

• Chrome 79 on macOS 10.15.2
• This issue does not appear in Chrome Canary v81, so it might be a browser issue
• Colleagues using Chrome 79 could not reproduce this issue
