Description

Reproduction:

Go to https://gist.github.com/lucaswerkmeister/28608c3667a7064455152959a6e0e4cc and take a query from there.
Run it (it takes some time)
Scroll down for results.
Observe that scroll jumped several rows past the start of the data.
Try to scroll back.
Observe weird behavior, e.g. scroll jumping back and forth, getting into endless loops, etc.

It seems to be part of a series of GUI changes that deteriorated the general impression of the Wikidata Query Service.

This is regrettable as the otherwise excellent service is an enhancement to the Wikidata experience.

To avoid confusing users, maybe all changes of the last two weeks should be roled-back.
