Operations dropbutton broken (wrong language)

Hi!
The problem is quite similar to this issue but I think is different because is not inside a view.

When I try to edit or delete a translation through the Bootstrap dropdown I get the wrong page.
This is happening with nodes and taxonomy term in the same way.

Step to reproduce.

• Create a node.
• Create a translation.
• Go to the page node/X/translations and try to use the dropdown operation to edit the translation or to delete the translation.
• What you end up with is the page to edit the original content or to delete the entire node (not only the translation).

This is not happening with the administration theme (seven).
In the markup i can see these differences:

Seven, editing the taxonomy term french translation.

<a href="/fr/taxonomy/term/12/edit" hreflang="fr">Edit</a>
<a href="/fr/taxonomy/term/12/delete" hreflang="fr">Delete</a>

Bootstrap, editing the taxonomy term french translation.

<a href="/it/taxonomy/term/12/edit" id="dropdown-item--3" class="hidden" hreflang="it">Edit</a
<a href="/it/taxonomy/term/12/delete" hreflang="it">Delete</a>

Bootstrap seems to use always the default site language.

Thanks in advance.
