issue #7787 Doxygen 1.8.18: Markdown tables not working in ALIASES anymore?

The artificial newline characters in ALIASES (`^^`) or better said its doxygen replacements (`\\_linebr`) were not seen by the markdown parser as line terminator and as a consequence there was no table seen (it was just 1 long line, without header / data lines)..
