The preview for math formula has stopped working since `7a9e8fd6221515b48f45ba29d3f102eb899f1e33` from ticket `T380079` from the Extension:Popup
Added the `href` attribute to the Math node.
The value must be a complete Uri to a local page with a title.
The value is taking from `node.baseURI`.

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.

The Extension:Popup preview was only working in SVG mode.
Added a new selector for the preview in MathML mode while keeping the old one working.
The selector for the preview in MathML works via the href attribute.

Enable popup extension for annotated math expressions. The popup shows a short summary of the formula and is generated via the Popup API introduced with I65fcbf25ac5818f6c649daf494c719921247e8f5. It is a follow up of Iefe98c1f0422dbf034e385b1a41a859d030a2cf4.
