Problem: Currently, bot edits are not marked on RevisionSlider. As users know that bots wouldn't do vandalism on purpose, they can skip patrolling bot edits. If bot edits would be marked on RevisionSlider, this would make it easier for patrollers to skip bot edits when they use RevisionSlider to go back in the version history and save them a lot of time.
Solution: On the RevisionSlider, bot edits are marked/made visible.
Background: This is part of adding the revision slider to the revision diff page. The revision slider is a feature that adds a visualization of all revisions to the compare screen.
The revision slider was originally prototyped by the WMF Community Tech team and then handed over to the WMDE TCB team, as it is also a solution to fulfill a wish of the German Community Wishlist: https://de.wikipedia.org/wiki/Wikipedia:Umfragen/Technische_W%C3%BCnsche_2015
