fluid_styled_content: Standard header doesn't use PAGE_TARGET
If you set the option "styles.content.links.target" in the Constants, it will not change the link target for header links.
Tested with TYPO3 8.4.0-dev
Updated by Patrick Broens about 7 years ago
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.
