Locale Partially Effective: Dictionary Errors in pt-BR, pt-PT, and ko

I tried to find an open or closed issue that addresses this and didn't find one. I've been around GitHub, but whether this should be a discussion, pull request, or something else...I'm not all that knowledgeable about where this belongs.

This was brought to my attention through an SO question for the R version, but it's also an issue in Plotly JS. The question is here. The person that asked that question added it to a current issue for that version of Plotly. You can see that here. I realized what was wrong when I compared the language pt-BR to other languages that rendered correctly (de or es, for example).

Wherever dictionary words are rendered with a colon, it is incorrect both in English and the locale language. For example, median: "mediana". This should be "median:":"mediana:" for this to work.

If I've caught them all, these are the English versions that are documented incorrectly (set up for a copy, paste, and regex):
'close',0'high','incoming flow count','kde', 'lat', 'lon','low','lower fence': 'limite inferior','max','mean ± σ','mean','median','min','new text','open','outgoing flow count','q1','q3','source','target','upper fence'

It looks like pt-br, pt-pt, and ko.js have this issue. I just did a find-grep for ',median:'.

This example, using pt-BR (and an example on the Plotly JS site), appears to render correctly, but that's because none of the errors in the JS are shown.

If you look at the tooltips or label with a colon in this CodePen, you'll see the issue.

From this CodePen, It should look like this:

Esamina i dizionari locale di pt-BR, pt-PT e ko.js, iniziando con una ricerca di chiavi del dizionario come median che vengono sottoposte a rendering con i due punti. Confronta le voci interessate con le versioni inglesi e gli esempi elencati. Il lavoro è completato quando le etichette contenenti i due punti vengono sottoposte correttamente a rendering nei tooltip e nelle etichette segnalati per tutti e tre i locale.
