  - Fix for Preview has wrong location in MathML mode
    
    The previewin MathML mode was always at the left side of the website.
    Added values for `node.offsetWidth` and `node.offsetHeight`.
    Values are taken from `node.getBoundingClientRect()`.
    Cleaned up if-clause(node.dataset.title) as it is not needed anymore.
    In-lined IsValidId funtion as there was only one remaining reference.
