When I use transcluded page which has tags <translate>...</translate>,
the page already have those same tags, the page added to the top page, has unhidden tags
You can see that on page https://vedopedia.witches-empire.com/wiki/Раз
Strange, but those two pages have same tag <languages/>, when the transcluded page comes without it. In my opinion, if the page prepared for translation, marked for translation or not yet, but has tags <translate>...</translate>, suppose to be transcuded without those tags.
