We have also seen this kind of error with the Azerbaijan Airline flight to Grozny which Russia shot. Due to electronic warfare the positions on flightradar didn't make sense in the early hours, until they reconstructed a more plausible path.

Flight J28243 was scheduled to operate from Baku to Grozny. The aircraft departed Baku at 03:55 UTC. Valid ADS-B position data was received from the aircraft until 04:25 UTC when the flight encountered significant GPS interference. The aircraft stopped sending positional data altogether for the period between 04:25 and 04:37. Between 04:37 and 04:40 the aircraft sent likely erroneous position data. Flightradar24 receivers did not receive data from the aircraft between 04:40 and 05:03 and a second gap from 05:04 to 05:13 . From 05:13 until 06:07 all data received from the aircraft lacked positional information. From 06:07 UTC through the end of the flight at 06:28 position data was received from the aircraft.

This is most likely to be the same kind of error.
