[Mis-use/Bug] How to correct wrong display of data when not showing in the editor?

[Hungerburg (Asa Hundert)]

This is fall-out from a global vandalism attack of todays. Best do nothing.

The "OSM Standard tile layer" looks wrong (white lines, abusive comments etc.)

Just to reassure people, this latest vandalism is being dealt with. It needs to be done in one go as all the changeset objects are interlinked. As noted above, piecemeal reverts using tools such as Josm’s reverter plugin or https://revert.monicz.dev/ won’t work because they will just restore something to a previously bad state.
