What it looks for

Arabic text falling back past the declared font family (measured, declared, or a webfont that failed to load)

How to fix it

Declare an Arabic-capable face: font-family: "IBM Plex Sans Arabic", "Noto Sans Arabic", Tahoma, sans-serif, or subset with unicode-range so Arabic gets a deliberate face instead of the system default.
