Have never personally seen that specifically happen, but I don't use Chrome (ever), and you are the only one who stated what browser is in use when it fails.
Google just implemented the next stage in their quest to declare the entire internet insecure in Chrome 68 that rolled out on 7/24/18, but I don't think that is the direct cause of the gray panel issue (assuming it is a Chrome browser caused issue)
https://arstechnica.com/gadgets/2018/07/todays-the-day-that-chrome-brands-plain-old-http-as-not-secu...Chrome may not be flagging eBay pages as insecure directly in the browser address bar, but there may be blocked mixed content, etc issues going on due to lingering HTTP content in listing descriptions. (I assume that "oh snap: icon is a Chrome and not an eBay thing.)
Since it seems to not be a widespread issue, and based on a very small dataset appears to be a Chrome issue, I wouldn't expect anything to get fixed any time soon given all the other more major broken things on the eBay website.
I found the page you screenshot and it displays fine in Firefox 31.
It is however, a relatively complex description section using lots of embedded CSS, faked frames, looks like a bunch of Microsoft Office (Word?) embedded XML garbage, and looks like it was run through GarageSale listing software.
I suspect the nature of that mess is what is causing the problem, and that most "clean" eBay listing descriptions are fine. As to what issue Chrome has with it - I don't know. Doesn't look like mixed-content problem as I speculated above. Maybe the MS XML stuff, or maybe it's choking on the CSS. [ calling an expert ---->

eBay user: "Doctor, Doctor!"
WebDoctor: "What?"
eBay user: "eBay often sucks when I use Chrome"
WebDoctor: "Then don't use Chrome."
