MT Enhanced Plugin using Google Translate does not include locked elements into translation

Locked inline elements are not included in the translation. Here you see the translation results from Google Translate via MT Enhanced and via the pre-installed plugin:

Since the pre-installed Google Translate plugin does include the locked element, I hope it is also possible with the MT Enhanced plugin. I've tried English>German and German>Spanish so far.

Here is an sdlxliff file with which you can test it:

Can you confirm that this is a general issue? Can you fix it? :-)
