Twenty Twenty: update selectors in get_non_latin_css()

[sabernhardt]

Several of the selectors used to set fonts are missing from the 'front-end' array:

.faux-button.more-link,
.entry-content .wp-block-cover-image p,
.entry-content,
.entry-content h1,
.entry-content h2,
.entry-content h3,
.entry-content h4,
.entry-content h5,
.entry-content h6,
.entry-content table,
.entry-content address,
.entry-content .wp-block-file

As a result, elements such as headings in the post content have the default sans-serif font (Inter variable or a system font) instead of the one defined for the language. Likewise, some elements in .entry-content would still display in a serif font.

The 'block-editor' and 'classic-editor' arrays may need updating as well (beyond removing .wp-block from headings in #56194). A ​comparison spreadsheet shows selectors from all three arrays against similar selectors in style.css.

Reviewing the languages would be good, too. For example, Persian (fa-IR) is included, but not the Afghanistan fa-AF locale.

add missing selectors (only)

In 56396.diff​, I did not remove any selectors that are not used for fonts in style.css, such as .entry-content p.

Thanks @sabernhardt! The patch fixes the issue on my side.

Before patch: Inter var used for h2

[audrasjb]

After applying patch: System font used for h2

@sabernhardt I'm wondering if we should separate the two part of this ticket: ship the selector change, but open a new ticket for the missing languages. Any thought?

[sabernhardt]

Adding support for more languages might be considered an enhancement, so the discussion and any change probably would be better in a separate ticket.

[audrasjb]

Alright, thank you 👍
Self assigning for commit then.

In 54314:

Twenty Twenty: Ensure the fallback fonts is applied to all content elements for non-latin languages.

This changeset adds missing CSS selectors to get_non_latin_css() function.

Props sabernhardt, audrasjb.
Fixes #56396.
