The Hebrew Wikipedia article Evolutionary history of life has a navigation template floating on the left-hand side. While editing in VE, it overlaps the text on the right-hand side.

Note how this is not always the case: https://he.wikipedia.org/wiki/%D7%90%D7%91%D7%95%D7%9C%D7%95%D7%A6%D7%99%D7%94?veaction=edit .

I see the same thing directly from RESTBase so this must be a Parsoid issue, not VE: https://he.wikipedia.org/api/rest_v1/page/html/%D7%94%D7%99%D7%A1%D7%98%D7%95%D7%A8%D7%99%D7%94_%D7%90%D7%91%D7%95%D7%9C%D7%95%D7%A6%D7%99%D7%95%D7%A0%D7%99%D7%AA_%D7%A9%D7%9C_%D7%94%D7%97%D7%99%D7%99%D7%9D

Most likely there is a problem with the wikitext used to render that template, because other floated templates on the wiki work fine.

So the wikitext is indeed to blame. The whole table is wrapped in a <span style="position:absolute;">, which the old parser throws away as invalid HTML4(?), but Parsoid allows it, so it only works in the old parser accidentally. I'll leave this here for the Parsoid team to look at, but most likely this is a known difference between the parsers.
