TYPO3 Core

styles.content.links.target has as description in constants.txt pointing the value is used for frames:

"Target for internal links: Should match the name of the content PAGE-object in TypoScript when used with frames. Most cases: set to "" (empty). If you have frames in the template set to "page""

Since fluid_styled_content is focussing on HTML5, this value does not make sense at all, since frames have been removed from the specification.

styles.content.links.target should be removed from constants.txt in fluid_styled_content including the use of this constant value in lib.parseFunc.ts, the only place where it is used. The typolink viewhelper does not take this into account also.
