Yes, it is! Sorry I oversaw that. Seems to be exactly the same issue, since I use the same SEO plugin. I’ll mark this thread as resolved and follow up with the other one.
I found a workaround by the way: In the SEO options of the SEO plugin in the page editor, you can set a title (the field “SEO Title”). Once I do that, that title shows up correctly on the frontend as the <title>-element of the page.
This may not be a perfect solution since that leaves you with a static, not translatable title, but at least it’s better than the result of the bug in question …
