"Continue reading" from embed tag problem

Hello,

Sorry for my bad english ! I’ll try to explain as best as I can.

I’ve put embed tag in the code to point to a certain URL on my own website, like this:
[embed]http://brunoouellette.ca/conferences/gagner-quand-ca-compte/[/embed]

The result:
French: http://brunoouellette.ca/conferences-2/pour-le-milieu-sportif/
English: http://brunoouellette.ca/sport-conference/

As you can see, the “read more” link in the generated embed is in french in the english page…

And it should show the title of the page in the link, it’s hidden because of the CSS “position”.

I’ve tried to translate “Lire la suite de” with XiliDictionary, I’ve also tried “Lire la suite de %s”, “Continue reading %s”… Nothing’s working…

I’ve tried to modify the CSS on the link (class=wp-embed-more or class=screen-reader-text), it’s doesn’t work: my style is not executed, the only CSS I see in the console is: http://brunoouellette.ca/conferences/gagner-quand-ca-compte/embed/#?secret=HPqDMkno7Q

I’ve change the theme to test, same problem.

Someone have an idea of what’s going on ? What can I do to translate the link and to see the title of the page in it ?

Thanks a lot for your help !
