Prerequisites:

• Login as admin
• Go to Site administration -> Plugins -> Filters -> Manage filters
• Enable the "Multi-Language content" filter for content and headings
• Go to Site administration -> Language -> Language packs
• Install the german language pack
• Set your current language to english

Steps to reproduce:

• Go to Site administration -> Licence -> Licence manager
• Click "Create licence" button
• In the following form
  • Set an arbitrary licence short name
  • Set "Licence full name" to

    <span lang="en" class="multilang">Public Domain</span><span lang="de" class="multilang">Gemeinfrei</span>

  • Set an arbitrary licence source
  • Set an arbitrary licence version
• Click "Save changes" button
• Open the created license again for editing

Expected result:

• The "License full name field" still contains the multilanguage notation
• On Site administration -> Licence -> Licence manager and anywhere else where the license full name is shown, the multilanguage syntax is processed and the name is picked according to the viewer's current language

Actual result:

• The "License full name field" does not contain the multilanguage notation anymore, it just says "Public Domain"
• On Site administration -> Licence -> Licence manager and anywhere else where the license full name is shown, just "Public Domain" is shown. The multilanguage strings are lost.
