An example of a WebSite with a sluggish scroll (WebArchive and HTML)
First let me apologise in advance for duplicate bugreport if any. In particular this bug might be related to #165196.
Some WebPages (I have attached an example, but I don't know any public site with this problem) have a very sluggish scroll on the latest (late 2016) retina MacBook Pro w/ Touch Bar, when it works fine in Chromium & Firefox.
It is not a problem related to JavaScript as the scroll is as sluggish with JavaScript off.
I've joined the WebPage in two formats (Safari WebArchive & pure HTML).
For both formats, you’ll have to disable JavaScript for the content to stay in the page.
I can join another example of a WebPage with this sluggish scroll if needed.</pre>
