 Hi,

 I'd like to better understand how the prioritization of .mo files should
 be working, as the behavior seems backwards.

 Having a multi-language site, I'm getting wrong language strings under
 these circumstances:

 1. I place plugin translations for select languages under
    wp-content/languages/plugins/plugin-xx_YY.mo
 2. I select a language other than default
 3. WordPress seems to always load the site's default language .mo first
 4. Then when language is switched by a multi-lang plugin, the code in
 l10n.php merging in the translations seems to prioritize the original
 entries over the 'new' ones:

 https://core.trac.wordpress.org/browser/tags/4.9/src/wp-
 includes/l10n.php#L586

    At 590: $mo->merge_with( $l10n[$domain] );
    will override the newly loaded .mo entries (in selected language)
    with the ones loaded before (site's original language).

 And so I end up with a site that's mostly translated to the selected
 language with strings for the 'plugin' in site's original language no
 matter what I do.

 Since merge_with() always overwrites the entries, shouldn't it be used as
 $orig->merge_with($new) rather than the current $new->merge_with($orig) in
 l10n.php?

 Thanks,
 hnhn
