Pattern of the title during translation edit varies for different entities:

• Block: <em>Edit @type</em> @title [%language translation]
• Comment: Edit @type @title [%language translation]
• Menu link: @title [%language translation]
• Shortcut: @title [%language translation]
• Term: @title [%language translation]
• User: @title [%language translation]

There is test base class ContentTranslationUITest, and it provides a default test for checking HTML escape. There is also a test ContentTestTranslationUITest.

Using the default test in ContentTranslationUITest we check the title in ContentTestTranslationUITest. Rest of the entities override the default class.
