Install an AR build.

Steps:

Font size drop-down displays western numerals. Default zoom drop-down displays eastern arabic numerals I think.

All drop-downs should display the numbers in the same format.

Moving to the prefs UI, as this is just about how/if to call into the APIs, not what they're doing.

"We follow CLDR (and ECMA402 Intl.NumberFormat) default numerals for a locale. In case of Arabic, there's a debate over what should be default numeral system for ar and we know which one should be for each of the ar-* regions. So, I assume that Fluent used Intl.NumberFormat and its numeral system here and used eastern arabic numerals, rather than western arabic numerals. As we migrate more of Firefox to Fluent we expect all numerals to stay consistent. In case of the standalone dropdown with numerals, like in the screenshot, I'd expect it to be fixed by running the numbers via Intl.NumberFormat.format."
