Although the bug has been reported a while ago, it hasn't been adressed yet (probably due to not being labeled correctly). I checked the issue today on my bq Aquaris E5 (Ubuntu 15.04 OTA-8.5) and when trying to open .html files from the file manager, the browser is still not being suggested to open the file.
