Thanks for the report. This excessive travel was a problem in 5.1 but I thought it had been fixed. It's the Monotonic setting that is the problem. I've noticed it my self but not in 5.2.1. The Cura team will take a look.
I'm getting the same thing on 5.4. Changing the monotonic settings had no effect for me. Changing the combing mode from "Not in Skin" to anything else fixed it though. I was seeing the same pattern as above where it goes back to the same point after each short segment in a little jagged fill pattern. The print did finish but it created some visible artifacts from essentially ironing over the lightning infill and picking up some extra material on the nozzle.
Combing mode: Not in Skin -> ~7.5hr print time Combing mode: Anything else -> ~6.5hr print time
Other move settings selected: Retraction Minimum Travel: 1.5mm Max Comb Distance: 30mm Retract Before Outer Wall: Box checked Avoid Printed Parts: Box checked Avoid Supports: Box checked Travel Avoid Distance: 0.625mm Z Hop: Box not checked

Reproduction steps
I tried to slice an object consisting of a large, thin ring at its base - see the attachments for the 3mf project. Some noteworthy slicing settings:
Actual results
On the first layer of top fill starting on the infill in the ring, cura inserts a travel move back to the origin of the filled area after each fill line. This behavior can be observed in layer 17 of the attached project.
In this screenshot, you can see the travel moves back to the top-left corner after each fill line:
The printed object came out okay, but the unnecessary travel moves did take quite some time.
Expected results
The filled area should be filled in one go, i.e. after finishing one line of the filled patch, the slicer should continue immediately with the next adjacent fill line, without travelling somewhere else first.
