Importing .tmx with HTML formatting

I am trying to import a tmx with HTML formatting. The HTML is escaped in the tus ("&gt;" instead of "<" etc.).

After importing, the HTML tags are in the TUs, like this:

Hallo, <em>dies/em> ist ein sch&ouml;er Tag.

These tags persist even if I select "import without formatting".

I would like Studio to recognize the styles and treat them as tags, like using the HTML5 file type or embedded content processor. Should that not be possible, I would like to eliminate all inline tags and decode all HTML encoded characters. Is that possible within Studio?
