Path data errors must result in the element being rendered up until the error

E.g. the following image has an error in its path data:

<svg xmlns="http://www.w3.org/2000/svg"
aria-label="Linux Mint" role="img"

(Note the double M at the start of one of the paths)

The expectation is that everything else is rendered and that single path is not (since the error occurs right at the start).

I don't think we should fix this here. It's rather a missing feature of the svg-pathdata dependency: nfroidure/svg-pathdata#48

Anyhow, I think we should catch errors during the element processing, otherwise rendering entirely stops e.g. for bad input on a specific element.
