Description

Three consecutive edits [1] to [[Liverpool Street station]] show no change when viewing their diffs individually. In page history [2] and user contribs [3], the first edit is shown as increasing the page size by one byte; the second and third show no change in page size. Viewing the same page in Watchlist shows an increase in size of one byte for all three edits.

If there truly is no change, it should not appear in either history, contribs or watchlist; if there really was one byte added, it should be identified in the diff.

Version: 1.24rc
Severity: normal
