Looks like it was introduced in #14627.

@swissspidy Thanks for merging this pull request. The "Read More" string gets translated in the WordPress Editor now 👍 (Gutenberg v6.2 with updated translation files) but I noticed that the Frontend still shows the untranslated string from the server side code here:
https://github.com/WordPress/gutenberg/blob/master/packages/block-library/src/latest-posts/index.php#L70

Can you confirm this behavior? Any clue why the PHP string translation does not work?

[swissspidy]

@them-es Can you please open a new issue for that? Since the PHP files use the default text domain, WordPress looks for the translation of "Read More" in its own translations. However, WordPress core only uses "Read more" with a lowercase M, so that doesn't work.

There are two possible solutions:

1. Use "Read more" with lowercase M everywhere.
2. Update PHP code to add Gutenberg text domain.

Or perhaps just both :-)
