From console: window.customElements is undefined, so that means that they are using webcomponents, which aren't fully supported in Classic yet and disabled by default, but seems that even enabling them doesn't help in that case.

thanks hawkeye116477 for looking at this and laying out the context.

Is there any chance webcomponents get fully supported in Classic any time soon, like with the .10 or .11 release?

[hawkeye116477]

@LeeBinder I don't think that will be that fast, cuz especially looks like I'm the only one who wants to do that and some of the parts Mozilla done for Servo only. Currently I'm waiting for UXP next turn, I'll see what they do and try to port that.

[LeeBinder]

OK, gotcha, and again thank you for sharing the context - so much easier to apprehend and relate in that manner 👍

[LeeBinder]

@hawkeye116477 is the following a webcomponents issue, too, or should I open a new issue?

On https://www.mediamarkt.de/de/search.html?query=usb, the content which should be to the right of the sidebar is displayed below it. It is displayed correctly in WF current.

[hawkeye116477]

@LeeBinder No, it's different problem. You should open a new issue.

Ok thanks, will do. BTW, same issue with Firefox 56.0.2.
